ASHBURN, Va., July 30 (UPI) -- Offensive tackle Trent Williams, the fourth overall pick in this year's NFL draft, has come to terms with the Washington Redskins.

Williams was expected to join the Redskins Friday for their second day of training camp workouts.

The deal covers six years and is worth $60 million, with more than $37.5 million guaranteed, The Washington Post reported.

Williams, 6-foot-5, 315 pounds, is likely to immediately be inserted into the Redskins' starting offensive line. He would replace left tackle Chris Samuels, who retired after a 10-year NFL career.

Williams played collegiately at Oklahoma where he was an all-conference selection last year.
