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."
"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."
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.
