RICHMOND, Va. (AP) -- Washington Redskins coach Jay Gruden says defensive end Jason Hatcher and three other players will be sidelined when training camp practice begins Thursday.

Gruden said Wednesday that Hatcher, defensive end Stephen Bowen and receiver Leonard Hankerson are still recovering from knee surgeries, while backup guard Maurice Hurt is out of shape.

Hatcher, acquired as a free agent from the Dallas Cowboys, had arthroscopic surgery last month. He is expected to return quicker than Bowen and Hankerson, who had more significant injuries.

The coach says quarterback Robert Griffin III's physical condition is "not an issue" 18 months removed from major knee surgery. Says Gruden: "The key for him is to learn from his mistakes."

Gruden is leading a camp for the first time. He says he'll have "butterflies" making sure everything's right.
