NHL unhappy with missed offside call on Flyers goal in playoff opener

TORONTO - Colin Campbell says he's almost as upset as the Pittsburgh Penguins over a missed offside call that led to a goal in Wednesday's playoff opener with the Philadelphia Flyers.

The NHL's senior executive vice-president of hockey operations acknowledges that linesman Tony Sericolo erred in not whistling the play dead prior to Danny Briere's goal early in the second period.

The Flyers forward was sent in on a breakaway off a long pass from teammate Brayden Schenn that came immediately after a turnover in the neutral zone.

Campbell believes that Sericolo was in position to make the right call but thinks the quick turnaround affected his view of the play.

Briere's goal was the first for Philadelphia as it erased a three-goal deficit and beat Pittsburgh 4-3 in overtime. After the game, Penguins coach Dan Bylsma said the blown call wasn't responsible for his team losing the game.

Campbell says the incident could affect how director of officiating Terry Gregson handles staffing assignments moving forward.
