In the first surprise roster move of training camp, the Washington Redskins released linebacker Lemar Marshall yesterday and signed 34-year old veteran Randall Godfrey. Marshall had started all but three games the last three years but was deemed expendable with the arrival of London Fletcher and emergence of Rocky McIntosh. Still, it was assumed Marshall would make the team as a backup weak-side linebacker. Marshall said coach Joe Gibbs called him to Redskin Park on Monday night, when he met with Gibbs, assistant head coach-defense Gregg Williams and linebackers coach Kirk Olivadotti.
