Aaron Rodgers left the Green Bay Packers' game on Monday night against the Chicago Bears with an injured collarbone.
Sources say that Rodgers suffered a fracture of the collarbone on the play.
Rodgers returned to the Packers' sideline in the third quarter in sweats, but not in a sling.
Mike McCarthy said that no exact determination has made on Rodgers' injury and that he will undergo further tests.
ESPN's Adam Schefter reported on Tuesday that Rodgers suffered a small fracture of the collarbone and could miss three weeks.
