Celtics' point guard Rajon Rondo is one of the fastest players in the NBA, and he's ready to prove that in a race against Olympic gold medalist Usain Bolt.

"I challenged him," Rondo said on Friday night. "I told him I don't think he wants it, though. Yeah, I told him that - you don't want it.

"But I also told him that he might see me in 2012. He said, 'OK, see you there.' "

Boston coach Doc Rivers hopes that Rondo keeps his focus on basketball.

"If you put dribbling into it, then maybe Rondo has a chance," said Rivers. "I hope he was kidding, but you never know with Rondo."
