NAPA -- Punter Shane Lechler's absence from the Raiders' practice field is because of arthroscopic surgery on his left knee just before training camp started.

Lechler said Wednesday he was having pain and swelling during workouts before deciding "to have it cleaned out" about 10 days before the team reported to Napa.

Being ready for the regular season, Lechler said, is a foregone conclusion. Coach Dennis Allen said he expected Lechler to punt in a game before the preseason ended.

"I don't have any doubt (about the regular season)," Lechler said. "I'm going to leave it up to them about what they want to do."

In order to reduce the pressure on his left knee, Lechler has come into camp some 20 pounds lighter.

"I did a lot more running this year," Lechler said. "We weighed in last week. It was the lightest I've been since I've been a Raider. I needed to do that, I think, to make this procedure go a lot faster."

  • Running back Mike Goodson, taken to the hospital in an ambulance with a neck injury eight days earlier, was back on the practice field, making decisive cuts and looking as if he never left.

    "It felt good to be back out there running, moving around," he said.

    Allen said he expects Goodson to play against Arizona on Friday night.

    "I can't wait," Goodson said. "Whatever they give me, I'll make do with it."

  • Wide receiver Darrius Heyward-Bey made the play of the day with a tumbling catch in the end zone on a deep post pattern from Carson Palmer, splitting defenders Shawntae Spencer and Michael Huff.

  • The Raiders spent Tuesday going over the Dallas Cowboys tape and had a closed practice session. Practice Wednesday was in shorts and shells with no pads, as will be the case Thursday.

  • Linebacker Mario Kurn and wide receiver Duke Calhoun, who both sustained torn anterior cruciate ligaments Saturday in practice, were waived/injured and will be put on injured reserve once they clear waivers.

  • Players who sat out practice included Lechler, running backs Taiwan Jones and Rashawn Jackson, wide receiver Denarius Moore, tackles Zach Hurd and Ed Wang, center Stefen Wisniewski, linebacker Aaron Curry and defensive tackle Jamie Cumbie.

    Curry is in Los Angeles getting treatment on his knees, and Allen hopes to see him next week.

    Wide receiver Eddie McGee returned to practice after missing more than a week with a hamstring strain.
