According to a news release, William Keith, a crew member of the No.38 Front Row Motorsports/Yates Racing team in the Sprint Cup Series, and Matthew Huffstetler, a member of the No.01 Daisy Ramirez Motorsports team in the Camping World Truck Series, were found to have violated sections 12-1 (actions detrimental to stock car racing) and 19 (violation of the NASCAR substance abuse policy) of the 2010 NASCAR rule book.

NASCAR has suspended five crew members so far this season for violating its drug policy.

NASCAR President Mike Helton addressed the seriousness of the Edwards- Keselowski incident, in which Keselowski's car went flying upside down into the frontstretch wall after Edwards deliberately hit him from behind in the closing laps at Atlanta.

Helton also said NASCAR officials had several discussions internally as well as conversations with the stakeholders of the situation, including team owners Jack Roush (Edwards) and Roger Penske (Keselowski), before making their decision to place Edwards on probation for the upcoming races at Bristol, Martinsville and Phoenix.

Keselowski got his bell rung when Edwards intentionally bumped him from behind and sent his No.12 Penske Dodge flying upside down into the wall along the frontstretch at the fast 1.54-mile track.

Edwards was more than 150 laps behind at the time of the crash, due to a previous encounter with Keselowski earlier in the race. Keselowski clipped Edwards and shot him up to the track before he made contact with Joey Logano and then slammed into the wall.

Busch squeezed his way from fourth to first just after the first two-lap overtime restart. A seven-car pileup occurred just before the final lap when Jamie McMurray and Clint Bowyer made contact, forcing a second attempt to end the race. Busch held off Matt Kenseth and Juan Pablo Montoya in the final two laps for his third victory at Atlanta and the 21st of his career.

Kenseth finished second, followed by Montoya, Kasey Kahne, who led the most laps with 143, and Paul Menard.

Hornaday, the defending series champion, secured his 24th career pole with a lap of 177.721 m.p.h. He also won the pole at Atlanta in 2007 and '08.

Kyle Busch will start on the outside pole after posting a lap of 177.306 m.p.h. Busch is the defending race winner.

Earnhardt Jr.'s lap of 192.761 m.p.h. set a record for the fastest qualifying speed in the new Sprint Cup Series car -- the Car of Tomorrow. His Hendrick Motorsports teammate, Jimmie Johnson, held the record with a lap of 192.376 m.p.h. last October at Charlotte.

"It's really fast," Earnhardt Jr. said of his qualifying lap around the 1.54- mile track. "You just got to hang on. I think there's a lot of cars that can run that fast, but you just got to hang on to it." Earnhardt Jr.

Since his disappointing 35th-place finish in the season-opening Daytona 500, Jimmie Johnson has soared to fifth in the points standings with consecutive victories at California and Las Vegas.

Johnson's win at California came with a little bit of luck. The four-time defending Sprint Cup Series champion benefited from a late-race caution when he pitted just before the yellow flag was displayed. He then held off a hard- charging Kevin Harvick in the closing laps.

After a two-week break, the Camping World Truck Series returns to action at Atlanta.

The series kicked off their season on February 12 at Daytona, with Timothy Peters winning the 250-mile race in thrilling fashion. Todd Bodine held the lead on the final lap, but Peters shoved Bodine up the track to claim the top spot. He went on to score his second career victory in the series.

The Nationwide Series received more attention than ever during the month of February due to the hype surrounding Danica Patrick's foray into stock car racing. Now, it's back to the same ole humdrum for NASCAR's second-tier series until Patrick returns in four months at New Hampshire.

Without question, Patrick's first three Nationwide races have been a learning curve, but there's plenty more for the 27-year-old to study during her stock car crash course.

Jeff Gordon led a track-record 219 laps, but Gordon took two new tires only during his final pit stop. After putting on four tires, Johnson quickly chased down his Hendrick Motorsports teammate after a restart with 34 to go. Johnson finally passed him for the lead with 17 laps remaining and then cruised to his second consecutive victory. The four-time defending Sprint Cup Series champion won last week at California.

"It came down to pit stops," Johnson said. "I thought the race was going to come down to pit stops and who got a good restart. Kind of turned out that way, although the four tires I think helped us more than anything." Johnson recorded his 49th career victory, which moved him up to 12th on the series' all-time race winners list. He also set a NASCAR record for most wins on a 1.5-mile track with 1

Harvick led the most laps with 83, but a lengthy pit stop early in the race shuffled him back in the field. He took the lead for good when he passed Denny Hamlin just after a restart with 25 laps to go.

Harvick recorded his 35th career victory in the series.

On lap 84, Patrick bumped into Michael McDowell and then slammed into the wall coming out of turn two. McDowell slid up the track and made contact with Patrick again when he hit the wall. She took her car to the garage with heavy damage to the front end of it.

"The car in front of me was going really slow, and I caught him down the front straight," said Patrick, who was running 27th at the time of the incident. "He was just going slow, so I went to go underneath him as he drifted up to the wall, and then he turned down in. I guess I probably should have seen all the tape on the left rear bumper and said, 'I probably shouldn't be on the left rear bumper.' Sure enough, he turned down and then took us both out." Patrick made her last Nationwide star

Keselowski knocked Kevin Harvick off of the pole with a lap of 185.427 m.p.h.

"I don't know how it worked out, but the car must have been that good," said Keselowski, who claimed his fourth career pole in the series.

Las Vegas, NV (Sports Network) - Kurt Busch captured the pole for Sunday's Shelby American by easily breaking the track qualifying record at Las Vegas Motor Speedway Busch, a native of Las Vegas, demolished the record previously held by his brother, Kyle Busch, when he turned a lap at 188.719 m.p.h. Cooler than usual temperatures at the 1.5-mile track helped 18 drivers surpass Busch's 2009 record of 185.995 m.p.h.

"It was an unexpected lap, but looking back at some of the decisions [crew chief] Steve Addington made...I'm following his direction on some of the key things that maybe I've been missing with the [Car of Tomorrow]," said Busch, whose last Sprint Cup Series pole came in September 2007 at California. "To get a pole with the COT, this is my first one with this car. It's been that long." Addington served as Kyle Busch's crew chief at Joe Gibbs Racing last season, but moved over to Penske Racing to guide Kurt Busch's effort for the 20

One of the biggest stories so far in the early Sprint Cup Series season is the resurgence of Richard Childress Racing. No driver in the RCR stable finished better than 15th in points last year, in what was one of the most disappointing seasons in the organization's 39-year history. However, things quickly have changed, and team owner Richard Childress couldn't be more pleased to the start of a season than this one.

By Chris Symeon, Motorsports Editor Las Vegas, NV (Sports Network) - Cha-ching! Who will hit the jackpot in NASCAR this weekend when the Sprint Cup and Nationwide Series roll into Las Vegas Motor Speedway?NASCAR Sprint Cup Series Shelby American - Las Vegas Motor Speedway - Las Vegas, NV One of the biggest stories so far in the early Sprint Cup Series season is the resurgence of Richard Childress Racing. No driver in the RCR stable finished better than 15th in points last year, in what was one of the most disappointing seasons in the organization's 39-year history.

All three of RCR's drivers -- Kevin Harvick, Clint Bowyer and Jeff Burton -- have finished no worse than 11th in the first two races of 2010. Team owner Richard Childress couldn't be more pleased about the start of a season, with Harvick leading in points, Bowyer in second (-19) and Burton fifth (-31).

Harvick easily could have begun the year at 2-0. He held the lead for the final restart in the Daytona 500, but eventual race winner Jamie McMurray got a friendly bump from Greg Biffle to move in front with less than two laps to go. Then at California, Harvick lost a spirited battle with Jimmie Johnson for the win after brushing the wall in the final laps.

Johnson, the four-time defending Sprint Cup Series champion, benefited from a late-race caution when he made his final stop just before the yellow flag waved for an accident involving Brad Keselowski. He avoided falling a lap behind when he crossed the line ahead of then race-leader Jeff Burton to start the caution period. Johnson took the lead for good with 24 laps to go when Burton and the remainder of the leaders pitted for the last time.

Kevin Harvick chased down Johnson in the closing laps, but Harvick scraped the wall and ended up finishing 1.5 seconds behind. Burton was third.

Busch grabbed the lead from Greg Biffle as they came out of turn four on the final lap and then beat him to the finish line by 0.05 seconds for his third victory at California and the 31st of his Nationwide career.

A late-race caution for an incident involving Brendan Gaughan setup a green- white-checkered finish.

Logano, who was the second driver to make his attempt in the 49-car qualifying field, turned a blazing lap at 181.283 m.p.h. for his second consecutive pole at California and the eighth of his Nationwide career. The 19-year-old started on the pole and won here last October.

"I'm pretty much in love with that race car; it's pretty fast every time I get out of it, and it's won a lot of races," Logano said. "Hopefully, we can bring the [car] to Victory Lane here again." Logano's teammate, Kyle Busch, captured the outside pole after posting a lap at 179.906 m.p.h. to give Joe Gibbs Racing the front starting row. Busch will start on the front row in a Nationwide race at California for the fourth consecutive time.
