The Washington Redskins have released wide receiver Jabar Gaffney after several failed attempts to trade the 10-year veteran, a person with knowledge of the situation said Tuesday. Gaffney, whom the Redskins acquired via trade last summer, led the team with 68 catches for 947 yards, along with two touchdowns, in 2011, but he became expendable after Washington signed receivers Pierre Garcon and Josh Morgan in free agency this spring.
