The Seattle Seahawks are moving Bruce Irvin to linebacker.

Irvin will compete with Malcolm Smith for the starting job, which he's expected to win when he returns from his four-game suspension.

"He's extremely versatile, and that's why we've loved him from the start," Carroll said. "He's really fast. He's 250 pounds, and he's exactly fitting the right kind of body type to play outside backer in the 3-4 system. We're a 4-3 personnel system that plays 3-4 looks. He's extremely valuable for us."
