Loudoun County, VA (SportsNetwork.com) - The Washington Redskins have signed offensive guard Shawn Lauvao, wide receiver Andre Roberts and linebacker Adam Hayward.

The team announced the free-agent signings on Wednesday.

Lauvao missed time last season after having arthroscopic surgery on his left ankle in August but started all 11 games he appeared in for the Cleveland Browns. He started 44 of the 53 games he played for the Browns after they selected him in the third round of the 2010 draft.

Roberts, taken four picks ahead of Lauvao in 2010, played his first four seasons for the Arizona Cardinals and had 43 catches for 471 yards and two touchdowns last season. In 2012, he set career highs with 64 receptions for 759 yards and five touchdowns.

Hayward spent his first seven NFL seasons with Tampa Bay after being selected by the Buccaneers in the sixth round of the 2007 draft.

In 107 games with the Bucs, Hayward recorded 161 tackles, one sack and five passes defensed. He was the team's special teams captain for each of the last three seasons.
