Linebacker Patrick Willis joined the other members of the 49ers originally selected to the Pro Bowl in passing on the chance to play in the game and it seems his left thumb was a reason for his decision.

Willis posted pictures on his Instagram account that showed a cast on his left hand and Matt Barrows of the Sacramento Bee reports via a league source that the cast is a result of recent surgery on his thumb. Willis was not on the injury report heading into the NFC Championship Game, although there’s no word on whether he suffered the injury during the loss to the Seahawks.

Willis broke a bone in his right hand in preseason, but did not wind up missing any time during the regular season. It was the fourth time he’d broken a bone in that hand, but the left side issues are a new one for Willis. He also missed a couple of games this season because of a groin injury.

There wouldn’t seem to be much risk of Willis missing the team’s offseason work as a result of the surgery, although he may be limited at times once the 49ers start getting ready for next season.
