Green Bay Packers' quarterback Aaron Rodgers says he suffered a broken left collarbone in Monday night's game against the Chicago Bears.
While media reports have hinted that Rodgers would miss three weeks, he says he does not yet know how long he won't be able to play. Rodgers called his injury "significant" and says he feels "some pain."
He left Monday night's game after only a few plays, after the Bears' Shea McClellin tackled Rodgers while he was scrambling.
Packers' back-up quarterback Seneca Wallace replaced Rodgers. Green Bay lost the game, 27-20 and is now tied for first place.
The team's next contest is Sunday in Green Bay, against the Philadelphia Eagles.
