Three-time NASCAR Sprint Cup Series champion Jimmie Johnson was a late arrival at Daytona International Speedway, but managed to run a handful of laps in the No. 99 GAINSCO/Bob Stallings Racing Pontiac Riley he will share with Alex Gurney, Jon Fogarty and Jimmy Vasser.

"I had a few laps today, and I will be back in the car again tomorrow," Johnson said. "The guys were nice enough to get me a few laps this afternoon to give me something to sleep on tonight. I'm not in these cars too often, so it's nice to do a few laps, look at some data and come back tomorrow and be ready."

While Johnson is looking for an unprecedented fourth consecutive NASCAR crown in 2009, he also wants to win the Rolex 24 for the first time.

"I'm here to win, that's what we're all here for," said Johnson, who finished second in both 2004 and 2008. "I've been on the second step twice now. It's such an accomplishment just to finish this race, so to be there in Gatorade Victory Lane and be part of the ceremonies is great. But second in anything is first loser. It's fun, but it's not the most fun."

Rob Finlay had a scare late in the afternoon when he cut a tire and spun in the No. 2 Childress-Howard Motorsports Pontiac Riley, but he missed hitting anything and escaped with only bodywork damage. He will co-drive in the Rolex 24 with three-time winner Andy Wallace, IndyCar Series regular Danica Patrick and NASCAR Sprint Cup Series driver Casey Mears.

The "Roar Before the Rolex 24" concludes Monday with a pair of sessions for both the Rolex Series and KONI Sports Car Challenge, beginning at 9 a.m. Official practice and qualifying for the 47th Rolex 24 At Daytona begins on Thursday, Jan. 22.
