Reportedly, WR/KR Josh Cribbs, formerly of the Cleveland Browns was brought in to Oakland, passed his physical, and the Raiders extended a contract offer to him. Cribbs did not sign as at least 3 other teams apparently showed interest soon after.
Cribbs was almost exclusively a special teams player in 2012, and battled through his knee injury. In 2011 he caught 41 balls for 518 yards. Cribbs has 11 special teams touchdown runbacks, 8 on kickoff returns and 3 on punt returns, in his eight year career thus far.
