Mastrud, 25, appeared in 14 games with Miami last season, playing 100 snaps. He wasn't targeted in the passing game and is purely a blocker. The Raiders also claimed WR Andre Holmes off waivers from the Patriots. To make room, Oakland released TE Mickey Shuler and DB Akwasi Owusu-Ansah.

Just a height-weight-speed project, 25-year-old Holmes has bounced around since going undrafted out of Hilldale. He has two catches in seven NFL games.

It's meant as a compliment, but Criner lit up pad-less workouts last offseason before not doing much of anything in the preseason or regular season. Standing in at 6-foot-3, 214 pounds with 4.37 wheels, Butler has always looked good in practice, but didn't do much on the field for San Diego State. The preseason will be his first real test.

Raiders rookie minicamp ' which was pad-less without hitting ' was the first time Hayden had practiced since suffering a torn heart cavity in a freak November collision. "The only time I think about it is when somebody asks me," Hayden said. "But when I'm on the field I don't think about it. I think about the play, and I think about the coverage. I've put it past me." Hayden's final test will be taking live hits, but the injury shouldn't be an issue going forward.

McGee was arrested for DUI and marijuana possession at Oklahoma, and was also suspended for unspecified rules violations. "We've had a lot of conversations," coach Dennis Allen said. "I think he understands the mistakes he's made. He's ready to learn and move on from it." Much like Buffalo's Da'Rick Rogers, McGee should be subject to a "one strike and you're out" policy.

Wilson reportedly looked like a "seasoned veteran" at rookie minicamp, throwing the football with placement and velocity. He'll look even better in preseason games because Wilson stands tall and firm in the pocket and isn't gun-shy under pressure. "Throwing the ball, he's done a nice job," said coach Dennis Allen. "I don't have any question about his arm strength and his accuracy."

NFL Films' Greg Cosell has separately compared Murray's playing style to DeMarco Murray's. The inference is the sixth-rounder with 4.38 wheels has terrific straight-line speed, but will struggle to make NFL defenders miss. Murray does pack power at 6-foot-3, 223 pounds, and that's what the Raiders want in new OC Greg Olson's gap-blocking scheme. Murray should make the final 53.
