DAYTONA BEACH, Fla. (AP) -- Defending Sprint Cup series champion Tony Stewart has captured the Coca-Cola Zero race for the fourth time under the lights at Daytona International Speedway. It's his third win of the Sprint Cup season. Stewart moved from ninth to fifth in the Sprint Cup standings.
Daytona 500 winner Matt Kenseth started from the pole and had the lead on a restart with three laps to go. But after starting in the number-42 spot, Stewart passed Kenseth late to take the flag for his 47th career victory. Jeff Burton came on to finish second.
Kenseth was trying to become the first driver since Bobby Allison in 1982 to win both races at Daytona. He wound up third after leading for 89 of the 160 laps.
DAYTONA BEACH, Fla. (AP) -- NASCAR has temporarily suspended driver AJ Allmendinger after he failed a drug test.
Allmendinger wasn't allowed to drive in the Sprint Cup race at Daytona International Speedway. Sam Hornish Jr. flew in from Charlotte just before the race and took his place behind the wheel of the No. 22 Dodge for Penske Racing, and finished 33rd.
Allmendinger has 72 hours to request that his B sample be tested.
Driving his first season for Roger Penske, Allmendinger ranks 23rd in Cup points. He is the most prolific driver to be suspended under NASCAR's substance-abuse policy since Jeremy Mayfield in 2009.
