Per Adam Caplann, Michael Bush is almost certain to return to the Raiders in 2011. Michael Bush spent his entire first season on the non-football injury list and he wouldn't have accrued the four seasons necessary to become a free agent. This conflicts with Jerry McDonald's report that his first season would count and he would become a free agent if the new rules allow players with four seasons to become free agents. I trust Jerry McDonald, but I have heard if the rules remained the same under the new collective bargaining agreement he would not become a free agent. There is also the possiblity this provision could be changed in the new labor deal.
