Wide receiver Andre Roberts will join the Redskins after agreeing to terms to a contract with them, according to a report from the Washington Post.

Roberts will be viewed as a slot receiver in Jay Gruden's offensive attack.

Roberts can't sign any deal until free agency begins at 4 p.m. on Tuesday.

Taken in the third round of the 2010 NFL draft, Roberts caught 182 passes for 2,123 yards and 11 touchdowns in four seasons with the Cardinals.
