Cubelic, now an analyst for ESPN and SEC Network, was providing color commentary from the scrimmage Saturday at Jordan-Hare Stadium. He has set up a GoFundMe page for Klein. The description says: "Severe back pain led to an MRI that revealed spots on his lower back. Unfortunately, Jeff’s condition has rapidly become more drastic and equally challenging to the doctors since his admittance."

Klein is at Piedmont Columbus Regional in Columbus, Georgia, according to the GoFundMe.

Klein played for Auburn from 1999-2001. He was 97-for-197 passing in his Auburn career, throwing for 1,139 yards and seven touchdowns.

"If you have had the unforgettable pleasure of spending time with Jeff & (his wife) Adrienne, one can bet that you were smiling big or laughing until you cried," Cubelic wrote on the GoFundMe page. "You would always leave them with feelings of being uplifted, encouraged, and thankful to call them your friends."
