BAGSHOT, England — The San Diego Chargers began their comeback after a poor start to the season with a win over the Jets. Now they'll have to beat jet lag to get back to .500.

The Chargers (3-4) arrived in London on Monday to prepare for this weekend's regular-season game against the New Orleans Saints at Wembley Stadium. They had their first practice — minus running back LaDainian Tomlinson — today.

"A couple guys struggled getting to sleep last night," wide receiver Vincent Jackson said at the team's training base in rural England. "Hopefully tonight we'll be able to get to bed about the right time and get up tomorrow feeling a little better."

The change in time zones was made a bit easier because the players flew to London right after Sunday's 23-14 loss to the Buffalo Bills, a difference of five hours from the East Coast rather than eight from California.

Still, they had practice as usual on Wednesday.

"Some guys were wide awake at 3 in the morning and some guys slept through the night last night," Chargers coach Norv Turner said. "I think it was good for our guys to get out and move around. Hopefully that will help them sleep tonight."

Tomlinson, nursing a toe injury he picked up early in the season, skipped practice. Tomlinson hasn't scored in the last three games, nor has he rushed for more than 100 yards since a Sept. 28 win over Oakland.

"We're on a schedule that he's been on that gives him a chance to be the healthiest before the game," Turner said of his star running back. "He has not practiced on Wednesdays (lately). He will practice tomorrow."

Wide receiver Buster Davis also missed practice, while receiver Chris Chambers and linebacker Jyles Tucker had limited practice.

"He (Chambers) did some things well," Turner said. "I'm not sure where he's at. The biggest thing about after a guy goes out and practices is how the injury reacts to it and how he feels tomorrow. And I would say the same about Jyles Tucker."

Despite the new scenery and the change to everyone's body clock, Turner said practice went according to plan.

"We didn't have many mental errors today," he said. "I thought the focus was outstanding. We worked on one portion of the game plan today. Tomorrow we'll work on the red zone, third downs, some other things obviously we have to handle."

One of the main goals on Sunday will be to stop Saints quarterback Drew Brees, who will be facing his former team for the first time and is expected to keep the ball in the air.

"As a DB, you love to see that a quarterback throws the ball," cornerback Antonio Cromartie said. "They're a passing team, so that's a challenge and we love it as a secondary."

Turner, whose team started the season 0-2 before beating the Jets 48-29 in Week 3, is expecting the Saints to try a lot of what the Bills did last week.

"They are a spread-the-field, very complete pass offense," Turner said. "Some of the things that Buffalo did — spread us out, got the ball out quick and they were very high-percentage completion — I'm sure New Orleans is looking at."

Defensive end Luis Castillo and his fellow linemen will be the ones trying to pressure Brees and the offense. First, though, they'll have to get back to their best after the long flight to England.

"The biggest players are still a little bit in a catch-up mode," Castillo said. "You travel that far, a lot of us didn't get much sleep on the plane, and the last two days we've spent just trying to get on a normal schedule.

"I think practice kind of woke us up a little bit because, up until then, a lot of us were still dragging a little bit. Tomorrow will be a much better day for us in terms of being on a more regular routine after getting a couple good nights of sleep."

The difference in time had another, unforeseen affect on Castillo: his ability to watch Monday night football.

"I don't even know when it was," he said.
