Packers quarterback Aaron Rodgers said Tuesday he has a fractured left collarbone and has no idea yet how long he will be out.

The 2011 NFL MVP offered details of the injury on his weekly radio show on 540-AM ESPN. He got hurt after getting sacked by Shea McClellin on a third-down play during the Packers' first series while he was scrambling outside the pocket. He hurt his left, non-throwing shoulder.

''I do have a fractured collarbone. That's a significant injury,'' Rodgers said. ''We'll know more about the severity and the timetable later this week.''

Rodgers said he was holding out hope he would heal quickly. ''In this case, it was considerably more pain than I've felt in a long time,'' he added.
