The Facts: Bucs running backs continue to fall as Antone Smith is headed to IR with knee injury.

Diehards Line:Smith started in Week 9 in place of the injured Jacquizz Rodgers, who was already starting for the injured Doug Martin and Charles Sims. Smith will head to the IR with a knee injury and the Bucs have signed Russell Hansbrough off of their practice squad. It has been a brutal season for the Bucs running backs. Doug Martin is expected back soon barring setbacks.
