RAIDERS WHACK TROUPE

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.
