Defending Daytona 500 champion out of race

DAYTONA BEACH, Fla. -- Joe Gibbs Racing was leading the Daytona, running 1-2-3 with its stable of Toyotas.

And then, two-time Daytona 500 champion Matt Kenseth's car started to smoke.

Next, Kyle Busch blew an engine.

That left teammate Denny Hamlin as the sole JGR car on the track -- in first place.

Kenseth is the defending Daytona 500 winner and this season is running a new car for a different team. He spent 13 years with Roush Fenway Racing driving a Ford before the switch.

Busch has never won the 500.
