Matt Kenseth was sitting courtside at a Dallas Mavericks game only about 18 hours after winning the delayed Daytona 500.

Kenseth was introduced to the crowd during the first timeout Tuesday night as a man who needs a nap.

Before the game, Mavericks coach Rick Carlisle presented Kenseth with a basketball autographed by the defending NBA champions. Kenseth gave the coach a Daytona 500 championship cap from the Victory Lane celebration early Tuesday morning.

Carlisle joked that he knew a little about auto racing and that "winning the Daytona 500 is a big deal." Kenseth has done it twice.

Kenseth says he got only an hour or two of sleep after the race. He will be back in Texas for the NASCAR Sprint Cup race in April.
