Detroit Lions middle linebacker Stephen Tulloch will miss the remainder of the season with a torn ACL he suffered while celebrating a sack. Tulloch injured his knee in the first quarter of Detroit's 19-7 victory over Green Bay on Sunday. He returned to action shortly after but was unable to continue playing, spending the remainder of the game on the sidelines. http://sports.yahoo.com/news/lions-lose-lb-tulloch-season-170332493--nfl.html
After this happened to Gramatica while celebrating an extra point, I never expected to see it again...
