Tony Stewart drove his number-14 Chevy from the rear of the field to a victory in the Coke Zero 400 at Daytona International Speedway Saturday night.  "Smoke" passed points leader Matt Kenseth on the final lap and survived a huge wreck on the final frontstretch to earn his third win of the season.  The defending Sprint Cup champion qualified second but started 42nd after failing post-qualifying inspection for an illegal cooling hose.  Four of Stewart's 47 Cup wins have come at Daytona yet he's never won the Daytona 500.  Jeff Burton finished second while Kenseth's bid to become the first driver to score a season-sweep at Daytona came up short with a third-place run.  Joey Logano and Ryan Newman rounded out the top-five.

Just hours before the start of the race, NASCAR announced that Sprint Cup driver A.J. Allmendinger has been "temporarily suspended" from competition for violating the sanctioning body's substance abuse policy.  Sam Hornish Jr. replaced Allmendinger in Penske Racing's number-22 Dodge.  Hornish Jr. arrived in Daytona from Charlotte just in time to start the event and finished 33rd.
