Raiders release DT Gerard Warren

ALAMEDA, Calif. (AP) -The Oakland Raiders have released defensive tackle Gerard Warren after three seasons with the organization.

The Raiders announced the move on their Web site Thursday. Warren is the fourth veteran the Raiders have released in the past week. He follows running back Justin Fargas, defensive end Greg Ellis and receiver Javon Walker.

Oakland acquired Warren from Denver just before the start of the 2007 season in the first trade between the two rivals since Willie Brown came to the Raiders in 1967.

This move didn't work out nearly as well for the Raiders. Warren had 77 solo tackles and 10 sacks in 44 games with Oakland.
