"Chris will begin his rehab immediately," Packers Head Trainer Pepper Burruss said. "His return to action this year is uncertain."
The second-year linebacker made a name for himself in a memorable moment earlier this season. Gizzi, a U.S. Air Force Academy graduate, carried the American flag onto the field in pregame ceremonies before the Packers Monday Night Football contest vs. Washington Sept. 24. The contest was the first MNF broadcast following the terrorist attacks of Sept.11, and the image of Gizzi waving the flag has become part of NFL promotional videos including the MNF intro.
Gizzi, 26, spent two seasons with Denver on the reserve/military list while fulfilling his armed forces obligations. He appeared in 11 games for the Packers last season and made his first start vs. Tennessee.
