The NCAA's transfer portal officially opened Monday morning, and UCF's roster figures to see a major shakeup over the next 45 days.

Backup quarterback Mikey Keene announced his long-expected intention to transfer Sunday afternoon, and two defensive starters have since followed suit. The Knights (9-4) will be without those players as they prepare for the Military Bowl against Duke on Dec. 28.

Below is an up-to-date list — arranged in chronological order — of departures and commitments, one that figures to expand until the window closes on Jan. 18.

UCF lost two previous transfer commitments in the first week of January. Former USF linebacker Antonio Grier Jr. opted to follow Travis Williams to Arkansas, while Orlando native and former Alabama wide receiver Christian Leary made a surprising switch to Georgia Tech.

Additions

DB Fred Davis II

Once a top-10 national cornerback prospect, Davis played more than 500 snaps over three seasons (27 games) at Clemson. The Jacksonville native, who attended Trinity Christian Academy, recorded 32 tackles and four pass breakups in his Clemson career.

Davis (6-0, 200) will bring length and athleticism to UCF's group of cornerbacks, an option to replace the outgoing Davonte Brown on the boundary.

LS Gage King

Alex Ward, one of the nation's top long snappers, is departing for the NFL. He's already committed to participate in the Reese's Senior Bowl.

King (6-2, 245) will be brought in to add experience and to compete for the starting role next season on the Knights' special teams unit.

DB DeJordan Mask

Mask (5-11, 190) played in 44 games for Texas State and set a career-high with three interceptions during the 2022 season. The Texarkana, Texas, native totaled 136 tackles (85 solo) and 13 pass breakups across four seasons.

Per 247Sports, Mask was a two-star recruit out of Arkansas High. He was ranked 3,064th overall and 224th among safeties.

WR Chauncey Magwood

A mid-year enrollee in January 2021, Magwood appeared in 25 games for Kentucky the past two seasons but logged just eight receptions for 104 yards. He caught his first career touchdown in the Wildcats' opener against Miami (Ohio) and had two catches apiece against Florida and South Carolina.

Magwood, who visited UCF the weekend of Dec. 16-18, held 24 Division I offers out of Leesburg (Ga.) High. The consensus three-star recruit was 86th among wide receivers in the 2021 graduating class, per 247Sports' composite rankings.

OL Marcellus Marshall

Marshall (6-6, 330) started every game at left tackle for Kent State this season and earned All-MAC first team honors.

UCF emerged victorious in a recruiting battle that also included Colorado, where former Kent State head coach Sean Lewis is now offensive coordinator, and West Virginia, the Knights' soon-to-be Big 12 rivals and Marshall's hometown team.

The Knights have at least two offensive line vacancies; left guard Samuel Jackson and right tackle Ryan Swoboda are out of eligibility. Marshall, meanwhile, said he has three years remaining.

OL Amari Kight

For the second time since the transfer portal opened, UCF dipped into Alabama's depth chart and plucked a former prized Crimson Tide recruit.

Kight (6-7, 318) was a top-10 national recruit at offensive tackle for the graduating class of 2019, earning All-State honors at Alabaster (Ala.) Thompson. He was the No. 2 option on the blind side for Alabama this fall, logging more than 80 offensive snaps and serving as a regular on special teams.

Offensive line is a huge need for the Knights, who have shown a preference to shop in the portal at the position. Last year, UCF brought in both of its bookends — Tylan Grable (Jacksonville State) and Ryan Swoboda (Virginia) — from other Division I programs.

WR Trent Whittemore

A soon-to-be-second-generation Knight, Whittemore (6-4, 211) spent the previous four seasons at Florida. He logged 33 career receptions in 29 games for 425 yards and two touchdowns.

Whittemore appeared in seven games in 2022, but fell down the depth chart under first-year head coach Billy Napier. He started eight of 10 appearances the previous campaign for Dan Mullen, and Greg Knox following Mullen's dismissal.

Whittemore's father, Mark, played wide receiver for the Knights in the Division I-AA days of the mid-90s and was a primary target of Darin Hinshaw, hired Wednesday as UCF's offensive coordinator. Talent runs deep in the family; younger brother Creed, a 2023 recruiting target for the Knights before he signed with Mississippi State, was selected Friday as Mr. Football after a stellar two-way season at Buchholz High in Gainesville.

DB Jireh Wilson

Wilson played, arguably, his best game of his junior season against UCF this fall.

The 6-foot-3, 219-pound safety snatched an interception and secured a fumble recovery in the first half of East Carolina's 34-13 rout over the Knights in October. For his efforts, Wilson was named the American Athletic Conference's Defensive Player of the Week.

A native of Jacksonville, N.C., Wilson has totaled 190 tackles, 16 TFLs, six sacks, four interceptions and 14 pass breakups in five seasons at East Carolina.

OL Bula Schmidt

Needing to fill a hole at center with Matt Lee's departure to Miami, the Knights plucked All-Mountain West Conference second team selection Schmidt from Fresno State.

The 6-foot-1, 294-pound native of Wahiawa, Hawai'i started all 14 games for the Bulldogs, and opened holes for Jordan Mims, the program's first 1,000-yard rusher since 2014. Fresno State selected Schmidt as an offensive captain for five games this past season, and he even caught a four-yard pass in an October win over New Mexico.

OL Drake Metcalf

Once regarded as one of the nation's premier interior line prospects while attending California high school powerhouse St. John Bosco, Metcalf's role was diminished in his third season at Stanford.

The 6-foot-2, 292-pound center appeared in all 12 games as a sophomore, but just three during the 2022 season before electing to redshirt. Following his visit to UCF, Metcalf told the Orlando Sentinel, "It’s very evident that UCF isn’t tip-toeing over the threshold into the Big 12. They’re preparing to blow the door completely off the hinges."

Metcalf has three years of eligiblity remaining and will compete for a spot along the Knights' rebuilt offensive line.

Losses

P Andrew Osteen

Osteen lost hold of the punting job in late September, but was called upon for a couple of clutch kicks inside the 20-yard line in a win over SMU. The redshirt senior punted 12 times with an average of 39.8 yards, a long of 50 and two touchbacks.

New school: Mississippi State

LB Terrence Lewis

The former five-star recruit never suited up for the Knights, nor Maryland the year before.

A pre-existing knee injury limited Lewis' reps in the spring, and he was arrested on domestic battery charges in May. Those charges were dropped a month later.

247Sports ranked Lewis (6-1, 200) as the No. 21 overall player in the graduating class of 2021, comparing him favorably to Tampa Bay Buccaneers star Lavonte David.

QB Mikey Keene

Since John Rhys Plumlee was named the starter in August, this was the anticipated outcome for Keene, a productive player in his two seasons at UCF.

Keene led the Knights to seven wins as a freshman, and three more this fall after entering in relief. He engineered two fourth-quarter scoring drives against Cincinnati, tossed three touchdowns at Memphis and lofted the game-winner to Alec Holler in the final War on I-4 at South Florida.

Described as a "Winner with a capital W" on several occasions this fall by head coach Gus Malzahn, the 5-foot-11,180-pound Arizona native threw for 2,377 yards and 23 touchdowns during his UCF career.

New school: Fresno State

CB Davonte Brown

UCF's top cornerback played through pain in his junior season, and did not have quite the dominant impact he had in 2021. However, his length (6-foot-2, 185 pounds), ball skills and abilities in man-to-man coverage will certainly be missed.

Brown, a Plantation native, started all 13 games, made 24 solo tackles and collected two interceptions, including one in this past weekend's AAC championship game against Tulane.

Younger brother Damari Brown, a four-star senior at Class 2M state finalist American Heritage, is considering Alabama and Miami among other programs. So it's possible the pair ends up being a package deal.

New school: Miami

LB Jeremiah Jean-Baptiste

Named one of the Knights' captains by Malzahn, Jean-Baptiste entered the fall as the only linebacker on the roster with any significant FBS experience. He missed three games due to injury, two to a concussion suffered in the road win over Memphis.

The 6-foot-2, 230-pound senior from Florida City finished the year as UCF's second-leading tackler behind All-AAC first team selection Jason Johnson. He registered 52 total tackles (37 solo), with five TFLs, one sack, four pass breakups and one forced fumble.

New school: Ole Miss

WR Ryan O'Keefe

Another captain, and another significant exit for the Knights.

O'Keefe is one of the team's most explosive playmakers, totaling 1,445 all-purpose yards during his senior season and earning All-AAC second team honors. The 5-foot-10, 175-pound senior from Austin, Texas, led UCF with 73 receptions for 725 yards while adding five touchdowns.

O'Keefe turned in, arguably, his signature performance during the Knights' Gasparilla Bowl win over Florida last December. He torched the Gators for 110 rushing yards, 85 receiving yards on seven catches and a crucial 54-yard touchdown with just over a minute left in the third quarter.

For his career, O'Keefe totaled 2,002 receiving yards and 15 touchdowns.

New school: Boston College

DB Philjae Bien-Aime

A redshirt sophomore who won a state championship with Fort Lauderdale juggernaut St. Thomas Aquinas, Bien-Aime spent three years at UCF but did not see the field.

He worked as a member of the scout team in both the 2020 and '21 seasons.

New school: North Alabama

WR Jordan Johnson

The St. Louis native, a consensus top-100 national recruit in the high school class of 2020, signed with Notre Dame but transferred to UCF after just 11 months.

Johnson (6-2, 185) made his debut in the second week of the 2021 season against Bethune-Cookman and saw action in five games. However, he was buried on the depth chart this fall and will again seek a fresh start.

CB Trevion Shadrick-Harris

Recruited to UCF by Josh Heupel's staff out of Sierra College in California, Shadrick-Harris earned All-NorCal League honors as a freshman in 2019.

The 6-foot-2, 195-pound redshirt junior participated in two games this year for the Knights, September clashes with South Carolina State and Georgia Tech. He will have two years of eligibility remaining as a graduate transfer.

DB Ah'mare Lee

Lee, a two-way contributor for all four years at North Miami Beach High, had a scout team role for UCF in 2021.

The former All-Dade County second team selection saw action three times this season, most recently the Space Game showdown with Temple in mid-October.

New school: Florida A&M

WR Joey Gatewood

A former top-50 national recruit Malzahn signed to play quarterback at Auburn, Bartram Trail grad Gatewood will seek a third transfer, though he'll have immediate eligibility as a graduate.

Gatewood was used primarily in special, short-yardage packages at UCF during Malzahn's first year in charge, logging 28 carries for 142 yards and one touchdown. The 6-foot-5, 220-pounder switched positions before the start of fall practices, but played just once in the win over South Florida.

In addition to Auburn and UCF, Gatewood had a six-game stint at Kentucky in 2020. He rushed for 62 yards and threw for 109 yards with an interception.

DE Karlis Bailey-Vice

The 6-foot-1, 200-pound redshirt freshman earned a spot in January 2021 as a preferred walk-on from nearby Bishop Moore Catholic and was a scout team regular. However, Bailey-Vice (6-1, 200) never saw game action in his two-year UCF career.

A studio art major, Bailey-Vice earned AAC All-Academic honors in June.

RB Anthony Williams

Opportunities were limited the last two seasons for Williams, a consensus three-star recruit from nearby Lake Brantley, given the Knights' crowded running back room. He did not see the field this fall, but carried the ball five times for 19 yards in a 2021 win over Bethune-Cookman.

Williams (6-0, 215) will have three years of eligibility remaining. He was recruited to UCF by Anthony Tucker, now the offensive coordinator/quarterbacks coach at Utah State, and new South Florida head coach Alex Golesh. Those could be sensible landing spots.

New school: Stephen F. Austin

OL Matt Lee

A three-year starter at center for the Knights, who attended Hagerty High in the shadow of the Bounce House, Lee's entry into the transfer portal on Jan. 2 comes as a bit of a surprise.

The second team All-AAC selection played in 36 games for the Knights since 2020, Josh Heupel's final season in charge. Regarded as one of the top centers in the country, Lee should be a hot commodity in the portal. And his impending exit suddenly leaves a massive hole in the middle of the Knights' retooling offensive line as they enter the Big 12.

New school: Miami

K Daniel Obarski

This comes as little surprise considering Colton Boomer ran away with the placekicking job in mid-September.

Obarski, who has two years of eligibility remaining, struggled with consistency and never fully gained the trust of Gus Malzahn's staff upon its arrival in 2021. He made 20 of 33 career field goal attempts for the Knights, none longer than 40 yards.

On kickoffs, the 6-foot-2, 200-pound senior averaged 61.4 yards per attempt, recording 140 touchbacks in 252 attempts.
