After racing at Rockingham Speedway for the first time this past Saturday, the Camping World Truck Series will join the Sprint Cup Series at Kansas Speedway this weekend.

Timothy Peters enters Saturday's 250-mile race at Kansas as the points leader. Peters' Red Horse Racing teammate, John King, held the top spot in the standings for the first two races -- Daytona and Martinsville -- but King, a rookie in the series this year, dropped to eighth in points after his 33rd- place finish at Rockingham. He was involved in an early-race accident there.

This isn't the first time that Peters has gone to Kansas with the points lead. He did so in May 2010. Peters finished 23rd at Kansas but continued to hold the top spot. He lost it one week later at Dover.

"Our season has been going well," said Peters, who has finished no worse than fifth in the first three races. "At this point, I would rate our season as an 'A-plus,' and we're running up front. If we keep executing, our win will come."

Peters' best finish in four truck races at Kansas is 14th, which came last June.

Justin Lofton is currently six points behind Peters, while rookie Ty Dillon is one marker behind Lofton.

Nelson Piquet Jr. comes to Kansas hoping for another impressive performance like he had at Rockingham. Piquet scored his first Truck Series pole there. The Brazilian native and former Formula One driver led a race-high 107 laps before a pit-road speeding penalty resulted in a seventh-place finish.

"After a weekend like we just had at Rockingham Speedway, I'm definitely ready to get back behind the wheel," Piquet said. "Last weekend really showed how competitive my team is, as well as Turner Motorsports as a whole."

Piquet started fourth and finished eighth in his first Kansas truck race last year. He drove for Kevin Harvick Inc. at the time. Piquet landed a ride at Turner for this season.

Brad Keselowski is the only Sprint Cup regular competing in this race. Keselowski has an opportunity to become the first driver to win a race in each of NASCAR's three national touring series at Kansas. Last year, he won the June Sprint Cup race and the October Nationwide event there.

Thirty-eight teams are on the preliminary entry list for the SFP 250.
