HERTFORDSHIRE, England — Colin Kaepernick briefly traded his celebrity status for that of a nearly anonymous tourist in London, much to his delight.

Only a “couple people” noticed him sight-seeing with his 49ers teammates on Tuesday’s day off, “but for the most part, it was peaceful, it was nice,” Kaepernick said Wednesday.

Chances are almost all of the 80,000-plus fans will recognize his No. 7 jersey Sunday when the 49ers face the Jacksonville Jaguars at Wembley Stadium.

Asked to name the most-memorable stadiums where he’s ever played away from home, Kaepernick listed only two: Boise State and Nebraska, both from his college days at Nevada.

“I don’t think anything’s going to compare to this weekend,” Kaepernick said.

Obvious omissions to his memory bank were losing the Super Bowl at New Orleans’ Superdome and winning the NFC Championsip in Atlanta’s Georgia Dome.

The atmosphere, he insisted, won’t distract him regardless of where it is. “You’re focused on what you need to do and be successful. You’re not worried about anything else,” Kaepernick added.

The 49ers have found success using a run-oriented offense during their four-game win streak. Kaepernick, meanwhile, hasn’t completed more than 16 passes in a game dating back to the season opener.

But he started hot in last Sunday’s 31-17 win at Nashville, doing quite enough to overshadow his incompletion-laden finish.

“To me, it all depends on whether we’re winning or not,” Kaepernick said in evaluating his recent passing displays. “If we’re winning, that’s successful. If not, something needs to change and we need to get better. The last (four) games we’ve won, so that’s all that matters.”

As unique as this overseas road trip is, Kaepernick feels his body has adjusted to the time change and that the 49ers are back to “our normal routine.”

What wasn’t normal was going nearly unnoticed in London. Can he do that back home?

“No, not in the Bay. I don’t try anymore.”

Defensive linemen Justin Smith (shoulder), Ray McDonald (biceps) and Glenn Dorsey (hamstring) stretched with their teammates but did not practice.

Safeties Eric Reid (ankle, right wrist) and Donte Whitner (knee) showed no hindrance in warmups and coach Jim Harbaugh said both players escaped serious injury last Sunday.

Harbaugh said the 49ers are enjoying their surroundings at The Grove resort, some 25 minutes north of London. “It’s a great place to set up camp,” Harbaugh said. “We have everything we need here. It’s a football oasis on the road.”

London native Lawrence Okoye’s popularity is booming, not just from teammates asking him for local tips but from the pack of reporters eager to share his story. Problem is, Okoye can’t play Sunday and is spending all season on the injured-reserve list, a result of a sprained knee ligament in the exhibition season. “It’s a frustrating time, but it’s a good time because I’m learning every day,” said Okoye, who’s been intensely studying other defensive linemen on game film the past couple months.
