Seahawks activate WR Paul Richardson, place Ricardo Lockette on IR

The Seattle Seahawks made a roster move Saturday, activating wide receiver Paul Richardson from the PUP list and placing Ricardo Lockette on injured reserve.

Lockette suffered a season-ending neck injury in Week 8 against the Dallas Cowboys. He underwent surgery to repair ligament damage and is back in Seattle where he will rehab.

Richardson was a second-round pick in 2014. He suffered an ACL injury during the divisional round of last year's playoffs but will now presumably be part of the rotation at wide receiver. Richardson caught 29 balls for 271 yards and a touchdown in 15 games last season. He played 47 percent of the team's offensive snaps.

Known for his speed, Richardson ran a 4.40 coming out of Colorado and said recently that he's posted even faster times after surgery.

Doug Baldwin, Jermaine Kearse and Tyler Lockett figure to still be the Seahawks' top three wide receivers, but Richardson should get some opportunities Sunday night against the Arizona Cardinals.
