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.
