All-Pro linebacker NaVorro Bowman has yet to undergo surgery to repair the torn ACL in his left knee.
Bowman also sustained damage to the MCL (medial collateral ligament), which will not require surgery. However, the ACL surgery cannot take place until the MCL has had some time to heal and the inflammation to subside.
Coach Jim Harbaugh last week said the ACL surgery would take place in two or three weeks.

When asked if he believes both Lattimore and Carradine will produced for the 49ers in 2014, Harbaugh said, “I have great hope for that, yes. I think there’s a path there, and nobody owes anybody a career in professional football. Your career is literally your business, but I have great faith that those men have what it takes.”
