The Buccaneers placed Smith (knee) on injured reserve Monday, Jenna Laine of ESPN.com reports.
The revolving door at running back in Tampa Bay has been precipitated by a spate of injuries, forcing Charles Sims (knee) and now Smith to IR. As a corresponding move, the Bucs have promoted Russell Hansbrough to the 53-man roster, which boasts three healthy RBs at the moment (also Peyton Barber and Mike James). Elsewhere on the injury front, Jacquizz Rodgers (foot) remained in a walking boot Monday, according to Greg Auman of the Tampa Bay Times, while Doug Martin has yet to practice since suffering a hamstring injury in Week 2.
