Another setback for Ravens running back Kenneth Dixon, who suffered his third knee injury in 12 months. Dixon is having surgery Tuesday after tearing his meniscus, according to a source. This comes after Dixon was already suspended four games by the NFL for violating the NFL's policy on performance-enhancing drugs. Baltimore is looking to sign Bobby Rainey to help with depth at running back. The only two locks to make the team are Terrance West and Danny Woodhead.
