Knox underwent successful surgery Tuesday to repair his fractured hand and is expected to miss a few weeks, Mike Garafolo and Ian Rapoport of NFL Network report.
Even with Buffalo on bye Week 7, Knox appears destined to miss at least some game action after suffering a broken bone in his hand during Monday's 34-31 loss to the Titans. The Bills haven't offered up a specific timeline for their top tight end's return, but Garofolo notes that the team has hope Knox "won't be out for long." A better indication of when Knox might play again could come when the Bills resume practicing Week 8, but expect the team to head into its next contest Oct. 31 against the Dolphins with Tommy Sweeney as its primary option at tight end. Kahale Warring is also likely to elevated from the practice squad to provide another healthy body at the position.
