San Francisco 49ers inside linebacker NaVorro Bowman is having surgery Tuesday to repair a torn ACL in his left knee. Bowman posted a photo of himself in a hospital gown on his Instagram account Tuesday morning with the caption, "Time for surgery." A league source confirmed Bowman's knee is being repaired by renowned surgeon James Andrews in Florida. The 49ers will have a presence there as Bowman begins his rehabilitation. Bowman suffered the injury while stripping the ball at the goal line in the 49ers' loss to the Seattle Seahawks in the NFC Championship Game. He also suffered damage to his MCL. Source: ESPN
