The Redskins have agreed to terms with fifth-year wide receiver Andre Roberts, formerly of the Arizona Cardinals, according to a person with knowledge of the situation.

Terms of the deal weren’t immediately available. Roberts can’t sign his contract until after the new league year begins at 4:30 p.m.

The 5-foot-11, 195-pound Roberts enters his fifth season out of The Citadel. A 2010 third-round pick, he has 182 catches for 2,123 yards and 11 touchdowns for his career. Roberts, who clocked a 4.36-second 40-yard dash out of college, last season recorded 43 catches for 471 yards and two touchdowns.

Wide receiver ranked among the Redskins’ needs with Santana Moss and Josh Morgan both free agents now. Washington hopes to add more weapons to the offense directed by Robert Griffin III. Pierre Garcon returns as the top wide receiver.

Washington also needs help on special teams, and Roberts has experience as a return man.
