NAPA – Raiders coach Dennis Allen said Wednesday he was extremely relieved that Mike Goodson was not seriously injured during a collision in Tuesday's practice that sent the running back to a hospital.

Goodson, who is vying to be the Raiders' backup to starter Darren McFadden, was taken off the field after the collision with linebacker Philip Wheeler. After a CT scan and MRI came back negative Tuesday night, Goodson was released and returned to camp headquarters and was "doing a lot better" Wednesday, Allen said.

"We care about all of these guys," Allen said. "Nobody wants to see anybody get hurt, especially something as serious as a neck injury. The fact that everything came back fine was obviously very relieving to us."

Allen said he wasn't sure how long Goodson, who was not seen around the practice field Wednesday, will be out. He said the collision, which occurred as Goodson attempted to catch a pass, was not a helmet-to-helmet hit but instead "a little bit of a freak deal."

"Mike kind of ducked a little bit. Philip kind of led with his shoulder a little bit and kind of lunged at him," Allen said. "It's things that happen in the game of football. It's an unfortunate occurrence. Fortunately, Mike is fine and we move on from it."

With running back Taiwan Jones still sidelined by a hamstring injury and McFadden not likely to play many snaps in the Raiders' preseason opener against the Dallas Cowboys on Monday, the bulk of the carries could fall to Lonyae Miller.

Miller, a 6-foot, 216-pound running back out of Fresno State who played in four games with the Cowboys in 2010, was signed by the Raiders to their practice squad in December and re-signed in January as a reserve/future free agent. "I would expect that he would be tired after Monday night's game," Allen said.

Injuries – The Raiders' list of nagging injuries has grown. Jack Crawford (foot), Aaron Curry (knee), Goodson (neck), Jones (hamstring), Shane Lechler (knee), Eddie McGee (hamstring), Denarius Moore (hamstring) and Richard Seymour (knee) did not practice.

Kicker Sebastian Janikowski also did not practice because of illness.

Darrius Heyward-Bey appeared shaken up after getting tangled with cornerback Ron Bartell going after a deep ball, but the wide receiver returned to practice.

Reprieve – The Raiders were scheduled to practice in full pads for a seventh consecutive day Wednesday, but instead they hit the field in shorts. It made for something of a half-recovery day, with no practice today.

The only player likely disappointed by this was Bartell. The veteran cornerback missed the first week of camp, so Wednesday was supposed to be his first day in full pads, an opportunity he said he was relishing after missing 15 games last year with a neck injury.
