Bobby Rainey

With Kenneth Dixon expected to be sidelined for much of camp with a knee injury and the Ravens already thin at running back, they are planning to sign veteran Bobby Rainey, who started his career with the team.

Rainey, 29, played last season with the New York Giants, appearing in 15 games and carrying the ball 17 times for 63 yards. He also had 20 catches for 153 yards, and returned both kicks and punts for the Giants.

Dixon, a second-year back, is believed to have a torn meniscus in his knee, according to sources. He'll have surgery today and the team will know more about the severity of the injury. This is Dixon's third knee injury since the Ravens took him in the fourth round of last year's draft. Dixon was already facing a four-game suspension to start the season. Without taking part in a big part of camp, it certainly brings into question how soon he can be ready after he returns in Week 5. Health-wise, he may be okay by then, but it's unlikely that he'll have a big role in the first two months of the season. Both Woodhead and West, but especially West, get a bump given this news.
