Packers quarterback Aaron Rodgers will undergo further tests on his injured shoulder Tuesday, but Adam Schefter of ESPN reports initial tests showed a small fracture in his collarbone that will keep him out about three weeks.
A source told ESPN's Ed Werder that Rodgers' injury "doesn't look good" and he could "possibly" miss the rest of the regular season.
