The Detroit Lions have announced that linebacker Stephen Tulloch will miss the rest of the season with a torn ACL.
The injury occurred when Tulloch celebrated a first-quarter sack of Aaron Rodgers in his side's 19-7 victory over the Green Bay Packers.
"Unfortunately, I got up in celebration and it happened," Tulloch told reporters. "But I ain't embarrassed by nothing. We all celebrate when we make a play."
The 29-year-old recorded 20 tackles and two sacks for the Lions this season.
