Stokley, who just turned 35, played in 11 games for the Seattle Seahawks last season and recorded 31 catches for 354 yards. Stokley also played for Mike Shanahan in Denver in 2007 and 2008.
His addition brings the Redskins' receiver total to 14. Earlier today, Washington signed Dante Stallworth and traded Jeremy Jarmon to the Broncos for Jabar Gafney.
Shanahan stresses depth and competition and the Redskins will certainly enter training camp with plenty of it at the wide receiver position. Santana Moss is a lock to make the team after leading the team in receiving the last six years and signing a new three-year, $15 million contract on Tuesday. Anthony Armstrong is entering his second season and had a strong first-year campaign.
But fourth-year receiver Malcolm Kelly is coming off of a year on injured reserve and has yet to live up to expectations. Second-year wideouts Brandon Banks and Terrence Austin also are on the roster, as is seldom-used veteran Roydell Williams. The team also drafted receivers Leonard Hankerson, Niles Paul and Aldrick Robinson in April.
