NAPA -- Raiders running back Mike Goodson was back with the team less than four hours after being strapped to a stretcher and taken to a hospital Tuesday after taking a hard hit delivered by linebacker Philip Wheeler.

According to a team statement, Goodson's "CT scan and magnetic resonance imaging (MRI) tests were negative. He returned to the team's training-camp headquarters at the Napa Valley Marriott."

Goodson caught a short pass from Carson Palmer inside the 20-yard line, turned up the field and was met by a crunching blow by Wheeler that knocked out his mouthpiece.

The running back was immediately treated by Raiders trainer Rod Martin and other staff. His face mask was removed, and teammates Denarius Moore and Taiwan Jones knelt down beside him as he was treated.

"You're down there, you're hearing the ambulance coming, you could start to panic and think the worst," Jones said. "I just tried to stay by his side and reassure him that everything's going to be fine. They're just being extra cautious for your health."

Napa Valley Fire Department personnel arrived first, and an ambulance was driven on the field once a tarp was cut free covering an entry gate at Redwood Middle School.

Medical personnel strapped Goodson to a board, his head and neck secure, and he was placed into the ambulance and taken to Queen of the Valley Medical Center. The procedure was normal and in accordance with rules regarding injuries to the head and neck.

Palmer said he threw the pass toward Goodson, watched him cut up field and was walking back to the huddle when he heard the collision. The Raiders carried on with their practice while Goodson was being treated.

"You don't want to say it, but it's part of the deal," Palmer said. "Sometimes they go off on stretchers. Sometimes they go off on the back of a little golf cart. Sometimes they go off on their own. It's just part of the game."

The hit by Wheeler was delivered with much more contact than the usual training camp hit, with players usually backing off after the initial hit rather than following through with full contact.

"I wasn't trying to avoid a collision. I was trying to hit him, but I didn't want to hit him hard like that," Wheeler said. "I didn't want to hurt anybody."

Allen said he would review the hit but expressed to his team that it was part of the game.

"Things are going to happen," Allen said. "It's unfortunate, but it's football. Obviously, as you get later into training camp and start seeing some of the heat, people get a little bit more irritable."

With Jones out with a hamstring injury, Goodson was getting more work than starter Darren McFadden, whom the Raiders are attempting to keep healthy for the regular season.

If Jones and Woodson are both out, McFadden's backup is first-year player Lonyae Miller out of Fresno State. He was signed to the practice squad Dec. 7.

  • Still out for the Raiders are Jones (hamstring), Moore (hamstring), wide receiver Eddie McGee (hamstring), linebacker Aaron Curry (knee) and defensive tackle Richard Seymour (knee). Defensive end Jack Crawford did not finish practice with a foot injury.

  • Palmer lobbied former college coach Pete Carroll to sign Terrell Owens, which the Seahawks did Tuesday.

    "Just knowing coach's style and the way he goes about teaching and leading his team, I thought that T.O. would be a great fit," Palmer said.
