Corey Dillon, who is 14th on the NFL's career rushing list, is likely to be playing for a team other than New England next season. Dillon's agent, Steve Feldman, said Friday that his client will ask the Patriots for his release and that the team is likely to grant it by March 2, the start of free agency. Dillon told The Boston Globe that he would probably retire, but Feldman, while acknowledging that retirement is a possibility, said it is unlikely. "Corey does not have to play, but he still figures he's got a couple of years left as a premier performer and the Patriots have been kind enough to understand that," he said. Dillon will not re-sign with the Patriots, Feldman said.
