Rookie Alex Daniels is making it known to coach Tom Cable that he will do whatever it takes to make the Raiders' 53-man roster.

Daniels is an undrafted free agent out of Cincinnati, where he played defensive end. On Wednesday, he made good on Cable's request that he give fullback a shot with projected starter Luke Lawton and backup Marcel Reece sidelined.

"If I've got to block for President Obama, if it's going to help the Raiders win, then that's what I've got to do because "... I just want to be one of them (53) guys," Daniels said. "If I've got to play fullback, then I'm going to be one."

Few fullbacks tip the scales at 275 pounds, but Daniels has experience in the offensive backfield. He played tailback for a spell at the University of Minnesota when injuries necessitated a change. He averaged 4.6 yards per carry and amassed 309 yards and five touchdowns in 11 games in 2006.

Also, Daniels said he was the No. 1 running back prospect coming out of Central Ohio and had scholarship offers from the likes of Texas, Ohio State and Oklahoma.

It's unlikely that Daniels will carry the ball for the Raiders. His primary role would be to clear a path for running backs Darren McFadden and Michael Bush.

"It's an experiment," Cable said. "He's got some running back in his background. We just feel like we need to continue to develop that position. "... We'll work with that experiment and see if something is there."

Daniels still views himself as a defensive end but isn't picky at this stage of his career.

"I'm fast and quick, I'm willing to learn," Daniels said. "That's the thing about it, if the running back coach tells me to go lift, I'll go lift. Whatever he needs, I'm going to get in the offensive playbook now and learn the plays and figure out what I've got to do to help the team."

  • Wide receiver Louis Murphy passed the required tests and returned to practice for the first time since suffering a concussion Friday. Murphy was kicked in the head accidentally by cornerback Nnamdi Asomugha and missed seven practices over a four-day span.

    Murphy made several impressive catches on balls across the middle and well downfield.

    "It's great coming out being able to make plays," Murphy said. "That's what the coaches want from me and that's what I'm here to do."

    Murphy said he suffered the concussion despite switching to a helmet that provides more protection.

    "I'm happy I did," Murphy said about switching helmets. "It could have been worse."

  • Receiver Darrius Heyward-Bey (rest), defensive end/linebacker Trevor Scott (wind knocked out) and cornerback Chris Johnson (rest) missed part or all of practice.

  • Rookie defensive end Lamarr Houston and tight end Brandon Myers engaged in a brief dust-up early in practice. Myers responded to Houston knocking over Myers, but teammates broke up the altercation before it got out of hand.

    "He's just coming here trying to prove himself," Myers said of Houston.

    "You expect that from a young guy. I'm young myself, too."

    Cable said he doesn't mind such confrontations as long as they don't get too heated.

    "It's going to get hot, you're going to get sore and tired and that's starting to kick in a little bit, so tempers are going to flare," Cable said. "But, at the end of the day, they're teammates and they took care of that right afterward. So, that was good."
