The Buffalo Bills officially ended running back Fred Jackson's season by placing him on injured reserve today, a day after it was revealed he suffered a Grade 2 MCL sprain in his right knee.
To take his place on the 53-man roster, the Bills promoted defensive tackle Jay Ross from the practice squad. Ross spent one game on the active roster earlier this season, Week Six in Arizona, before being released and brought back for his second stint on the practice squad.
The Bills will go into Sunday's game against Seattle in Toronto with just two running backs in C.J. Spiller and Tashard Choice. Coach Chan Gailey said Monday fullback Corey McIntyre could serve as a third running back if needed.
The team signed running back Zach Brown to the taxi squad today to give themselves some more depth at the position.
