The Tampa Bay Buccaneers Charles Sims will undergo surgery on the ankle he injured in practice. Sims is expected to be out for 12-14 weeks. This should be good news for Doug Martin owners, as Sims seemed the likely contender to carries in Tampa Bay. Bobby Rainey, Mike James and Jeff Demps are all vying for carries as well. Sims could be a worth add from the waiver wire depending on how the early part of the season goes.
