Willie Smith worked out for the Chargers last week.

He clearly made an impression.

The veteran offensive tackle signed a two-year contract Monday, joining the 53-man roster. Tackle Kenny Wiggins, who was just signed Saturday from the practice squad, was waived in a corresponding move. Undrafted rookie tackle Nick Becton, cut Saturday for Wiggins, cleared waivers and joined the practice squad.

Smith gives the Chargers some tackle experience behind, when healthy, starters King Dunlap and D.J. Fluker.

Listed at 6-foot-5 and 310 pounds, he has 10 career starts. Three came on the left side for the Redskins in 2011, the other seven to the right in 2012 for the Raiders. He spent this past training camp in Oakland but injured his back in a preseason game.

He is recovered from the injury, expected to practice for the Chargers on Wednesday.

Smith, 27, joins Mike Remmers at reserve tackle. Remmers made his NFL debut earlier this season, playing four snaps on Oct. 20 against the Jaguars. He suffered a high ankle sprain but returned to practice last week as a full participant.
