Washington Redskins center Cory Raymer will undergo reconstructive knee surgery and is out for the season.
Raymer first damaged ligaments in his knee during training camp and was ruled out for at least the first four weeks of the season. He rehabilitated himself and was close to playing again, but reinjured the anterior cruciate ligament doing agility drills in practice last Thursday.
Raymer, a six-year veteran out of Wisconsin, started 37 straight games for the Redskins before this season.

Gordon signed as a free agent with the Buffalo Bills last year and played in eight games, accumulating 38 yards on 11 carries. He also had one kickoff return for 11 yards. . . . The career of Kansas City Chiefs Pro Bowl guard Dave Szott could be over after his second serious arm injury. Szott tore biceps in his right arm in the season opener against Indianapolis Sept. 3. The injury at first was thought to be relatively minor, but now is said to be identical to the injury to his left arm last year that kept him out of the entire season.
