The Redskins have opted not to tender a contract to Quinton Ganther, and the second-year running back is now an unrestricted free agent.
Ganther had entered the offseason as an exclusive rights free agent.
Ganther emerged as a starter for the Redskins late in the 2009 season. He assumed a larger role on the offense following season-ending injuries to Clinton Portis and Ladell Betts.
Ganther started 4-of-7 games and posted 199 rushing yards and three touchdowns on 27 carries. He also caught nine passes for 99 yards.
Ganther's best game was in Week 14 at Oakland, his hometown. He posted 14 carries for 50 yards and scored two touchdowns.
Exclusive rights free agents are players with two or fewer years of NFL experience but cannot negotiate with other teams. Their rights belong to their current team provided they are made a minimum qualifying offer.
