The Oakland Raiders have released tight end Ben Troupe, a league source tells us.

Last month, the Raiders placed Troupe on injured reserve with a foot injury. 

A player may be released from injured reserve if the player is healthy, but the player also can file a grievance as to the question of whether he truly is healthy.

Troupe will become an unrestricted free agent if he clears waivers.

He was a second-round pick of the Titans in 2004, and he signed with the Raiders earlier this year.
