The Redskins have signed their top draft pick, second-rounder Trent Murphy.

Washington now has seven of its eight draft selections under contract. Third-round pick, offensive tackle Morgan Moses, remains unsigned.

Murphy, the 47th overall pick of the draft, agreed to a deal worth  $4.21 million over four years, including a signing bonus of roughly $1.44 million.

Murphy this offseason will vie for a spot in Washington’s outside linebacker rotation behind Pro Bowl bookends Brian Orakpo and Ryan Kerrigan.

Coach Jay Gruden expressed encouragement about the potential the 6-foot-5, 250-pound Murphy showed during the five minicamp practice sessions.

“He’s got a long way to go, obviously, but we’re excited to work with a guy that’s 6-foot-5-and-a-half and with room to get bigger and stronger and has the arsenal of moves that he has,” Gruden said last weekend. “He can counter-move. He doesn’t predetermine his moves when he rushes. He’s got a good spin move, he’s got an inside move, he’s got an outside. He uses his hands, he can get down – works his leverage. He’s got all the skill you want already, now it’s just a matter of keep developing, keep working on his get-offs and just keep developing him. We’re happy with that pick, there’s no doubt.”

The Redskins also announced they have released rookie free agent receiver Kofi Hughes and signed wideout Rashad Ross. Hughes signed with Washington last week and spent the rookie minicamp with the team. Ross is a 5-11, 179 Arizona State product, who signed as  an undrafted free agent with Kansas City last year, but didn’t record a stat.
