Aaron Rodgers' odds of playing in Week 13 against the Detroit Lions are "slim and none."

Rodgers injured his collarbone several weeks ago against the Chicago Bears.

The Green Bay Packers will instead start Matt Flynn.

Randall Cobb is unsure if he will be able to return to the Green Bay Packers' lineup this season.

Cobb is on short-term injured reserve with a leg injury.

"I can't make that call right now," Cobb said, per the Green Bay Press-Gazette. "Right now, today, I cannot play. I'm doing everything I can. I'm working my butt off in the rehab process. This is something that it needs time. It's getting better. There's still no timeline on when I can come back."

Aaron Rodgers is no longer in pain when throwing a football with his fractured collarbone.

Rodgers' decision on whether or not to play is due to risk evaluation and not pain tolerance.

Rodgers could need a three to five month recovery time if he takes a shot to the collarbone before it heals.

Rodgers is 15 days into a healing process that typically takes six to eight weeks.

Matt Flynn has returned to the Green Bay Packers, but is not thinking about whether he will remain beyond the end of the season.

"I don't think people are really thinking to next year or anything like that," Flynn said. "I know I'm here now. I'll do the best I can." 

Flynn has played for the Seattle Seahawks, Oakland Raiders and Buffalo Bills since leaving the Packers after the 2011 season.

Flynn will actually make $294,411 from the Packers if he remains on the roster for the rest of the regular season. 

Aaron Rodgers is pushing to return to the Green Bay Packers' lineup as quickly as possible.

Rodgers fractured his collarbone a week ago against the Chicago Bears.

Rodgers hopes to be back in time for a key Thanksgiving matchup against the Detroit Lions.

"I haven't given up hope on playing any week," Rodgers said, per ESPNMilwaukee.com. "It depends on how I heal and depends on what the next X-ray looks like. Obviously, this week is probably not going to happen -- not going to happen. (pause) Probably not going to happen."

The Green Bay Packers will work out Matt Flynn on Monday.

Flynn was recently released by the Buffalo Bills and was previously released this season by the Oakland Raiders.

Seneca Wallace started on Sunday for the injured Aaron Rodgers, but he injured his groin in the first half.

"I thought Scott Tolzien played as well as can be expected," McCarthy said.

Flynn was Rodgers' backup through 2011.

Scott Tolzien will start as quarterback of the Green Bay Packers next week against the New York Giants.

Seneca Wallace started the game and injured his groin in the first quarter.

Tolzien went 24-for-39 for 280 yards, one touchdown and two interceptions in just over three quarters.

"I thought Scott Tolzien played as well as can be expected," Mike McCarthy said. "He'll start against the Giants."

Clay Matthews returned to the Green Bay Packers lineup on Sunday and played a majority of snaps in their 27-13 loss to the Philadelphia Eagles.

Matthews struggled to make an impact while playing with a substantial club protecting his surgically repaired right thumb.

Nick Foles had a 149.3 passer rating.

"It's moreso difficult going out there with one hand than dealing with the pain," he said. "Obviously it's going to hurt, but that wears off. They assured me it would be very difficult to reinjure the hand being in a club with the protection that I have and how it's casted down. 

"But at the same time, that doesn't mean the pain goes away. So that's just a byproduct that I need to continue to push through, and I think I will. Obviously today's the first day that I had live reps and live action throwing it in there, and we're obviously pushing the timeline, too, as far as returning. So it'll continue to improve, and we'll move forward." 

Aaron Rodgers confirmed that he has a broken left collarbone, which could keep him out of the Green Bay Packers' lineup until December.

Rodgers and the Packers have not set a timetable for his return.

"We're still going through the process of testing," Rodgers said Tuesday on ESPN 540 in Milwaukee. "But we do know that the collarbone is fractured and we still have not talked about or discussed any long-term prognosis."

Rodgers will not need surgery on the injury that occurred in the first series for the Packers in their loss to the Chicago Bears.

"I'm in some pain," Rodgers told ESPN 540. "It's obviously disappointing what happened last night with the injury and the loss. ... Holding out hope this will be a quick heal, but this is a significant injury."

Rodgers went into the locker room and returned in the third quarter in sweats to a loud ovation from the crowd.

"When I walked back on that field -- I'm getting a little choked up here just thinking about it -- that was one of the top five moments of my career," Rodgers said Tuesday. "The reception I got from the fans was pretty special."

With Aaron Rodgers injured, wild speculation began that Brett Favre could return to the Green Bay Packers.

Favre is reportedly in excellent shape and the St. Louis Rams may have reached out to him following the injury to Sam Bradford.

Favre's agent, Bus Cook, "assured" Gabe Neitzel of ESPN Wisconsin that he "is retired."
