Tennessee Titans linebacker Keith Bulluck told the Nashville Tennessean Wednesday that Celtics point guard Rajon Rondo should be careful if he's honest about challenging Titans running back Chris Johnson to a footrace.

Johnson created a little Twitter-fueled frenzy when he posted that -- through Celtics guard Marquis Daniels -- Rondo had challenged the speedy Titans running back to a race.

Bulluck told the paper:

"Rajon Rondo doesn't want any piece of C.J. As a matter of fact, if you can get the message to Rondo, we'll match him bill for bill, whatever he wants to do. Our money is on C.J. I am faster than Rondo.''

For the record, Bulluck reportedly ran a 4.43 40-yard dash during a predraft workout. The Titans drafted Bulluck out of Syracuse in the first round (30th overall) of the 2000 NFL draft.
