Although Green Bay Packers coach Mike McCarthy said Aaron Rodger's injury is "week-to-week," one report indicates Rodgers may miss six to 10 weeks because of his broken left collarbone. Free agent Matt Flynn, meanwhile, cleared waivers on Tuesday without any team claiming him - including the Packers.

Rodgers suffered the broken collarbone on Monday in the opening series against the Chicago Bears.  He exited the game and didn't return.  ESPN's Adam Schefter reported the initial tests suggested Rodgers could miss around three weeks.  McCarthy acknowledged Rodgers had a broken left collar bone but said the team has a "week-to-week" mindset for the signal caller's return, ESPN reports.

"I'm relieved, no doubt," McCarthy told reporters on Tuesday, via ESPN.  "With the new information that was given today, everybody felt better about it.  How long?  We don't have our hands around a timeline yet, but I know Aaron is very optimistic and he'll do everything he can to get back in a timely fashion."

A report by Will Carroll, the lead writer for sports injuries at Bleacher Report, suggested Rodgers could be sidelined for close to two months.

"The normal time range for a fractured collarbone is six to 10 weeks," Carroll wrote on Tuesday.  "However, if the fracture is in a 'good' location and if there's no associated damage, it is possible for him (or anyone) to come back earlier."

The extent of Rodgers' injury is unclear, but both ESPN and Carroll see no indication that Rogers would need season-ending surgery.

In the meantime, Green Bay appears ready to proceed with backup Seneca Wallace under center.  Flynn, an ex-Packer under McCarthy, cleared waivers on Tuesday and went unclaimed. 

"I'm preparing Seneca to be the starter," McCarthy said. "That's the way our game planning has gone."
