Kedric Golston has signed his restricted free agent contract, the team announced on Friday.
The Redskins had tendered a contract to Golston, the team's third-year defensive tackle, on Feb. 26.
By signing the contract, Golston cannot be signed by another NFL team this offseason.
Golston becomes the third and final restricted free agent by the Redskins to sign the tender offer.
Shaun Suisham signed his tender on March 16 and Anthony Montgomery signed his tender on March 25.
Golston was a sixth-round draft pick by the Redskins in 2006.
He has started 25 games in three seasons and posted 83 tackles, 3.5 sacks and a safety.
Last year, Golston started 12 of 13 games and logged 44 tackles and a half-sack.
He also is a contributor on special teams units and he has a blocked field goal and a blocked PAT to his credit.
