SAN DIEGO - While severely disappointed with how uncompetitive the Chargers were against the New England Patriots, running back LaDainian Tomlinson says there's no need to panic.

The Chargers players returned to practice Wednesday for the first time since being routed by the Patriots three days earlier, and Tomlinson, a team leader, said he has no plans to address his teammates.

"I don't really feel like there's a need to say anything right now," Tomlinson said to the assembled media. "You guys want us to start panicking because we lost one game, and that's not what we're going to do. It's a long season, and we play football.

"The Patriots beat us and gave us a good whupping, but that's probably what we needed at the time."

Quarterback Philip Rivers also said that there was no reason for concern.

"We're 1-1, we're not 0-8," Rivers said. "I think that's important, that we don't blow it up. Nobody here is pleased with the way we played or trying to downplay the loss. But it is what it is. It's one game, and we're going to learn from it and get better."

Asked to pinpoint the problems, Tomlinson said he's the wrong person to ask.

"Not me, I'm not the coach," Tomlinson said. "I'm a player. So I'm going to do whatever I can to try and make it happen. Whatever is happening out on the football field, that's up to the coaches to pinpoint what's going on and what's not going on."

Wilhelm could sit

Coach Norv Turner isn't counting on starting inside linebacker Matt Wilhelm being in uniform for Sunday's game at Green Bay.

"I can understand where he's coming from," Wilhelm said. "It's not something to take lightly."

Wilhelm underwent an MRI exam on his injured calf Monday and was encouraged that a tear was ruled out. He said he's frustrated after suffering his second calf injury in less than six weeks. Tim Dobbins would start in Wilhelm's place.

Starting right tackle Shane Olivea also could be in jeopardy of missing the game after suffering a back injury. Either Jeromey Clary or Roman Oben would start if Olivea can't play.

Olivea also isn't pleased with the hit he took from New England linebacker Adalius Thomas.

"He kind of gave me a shot when I was unable to defend myself," Olivea said.

Safety Clinton Hart (hamstring) and linebacker Stephen Cooper (neck) also missed Wednesday's practice.

Defensive tackle Jamal Williams (elbow) fully participated in practice.

"Jamal is sore but he worked today," Turner said. "I think by Sunday he'll be ready to go."

Packers injury woes

A total of 13 Green Bay players missed all or part of practice. Among the players who missed the entire practice were cornerbacks Al Harris (back) and Charles Woodson (hip), defensive tackle Corey Williams (ankle) and tight end Bubba Franks (knee). Among the limited practice participants were starting defensive ends Aaron Kampman (rib) and Cullen Jenkins (wrist) and offensive left tackle Chad Clifton (ankle).
