Linebacker Patrick Willis, who declined an invitation to the Pro Bowl after the 49ers’ season ended with a loss in the NFC Championship game, appears to have undergone a procedure on his left hand or thumb.

Willis, who celebrated his 29th birthday on Saturday, posted photos on his Instagram account that showed him with a cast on his left hand.

Willis sat out the entire exhibition season after sustaining a fractured right hand during a practice early in training camp. Willis played in 14 games, missing two games due to a groin injury.

It is uncertain whether Willis sustained the injury in the 49ers’ 23-17 season-ending loss to the Seattle Seahawks. He was not listed on the injury report leading up to the 49ers’ final game.

Willis’ hand is not expected to keep him out of the 49ers’ offseason program, which is expected to begin on April 21.

All-Pro inside linebacker NaVorro Bowman is scheduled to have surgery to repair a torn ACL in his left knee in the coming weeks. The surgery will take place after Bowman's torn MCL has time to heal. The 49ers do not have a timetable on Bowman's return to action.
