It's been a little over a year since the sons of Joe Gibbs have lined up against each other on the race track. However, that is set to change this weekend with the running of the Darlington 200 Craftsman Truck Series race this Sunday.

Not only will Coy Gibbs, a regular in the #20 MBNA Chevrolet be in attendance, but his older brother J.D. Gibbs will be running the #48 Hot Rod Magazine Chevrolet.

Both Coy and J.D., sons of legendary NFL coach Joe Gibbs have raced cars and trucks since their graduations from college. As time has passed, J.D. has moved toward the business end of racing while Coy stayed firmly behind the wheel.

J.D. is currently the President of Joe Gibbs Racing, which fields the Pontiacs of current Winston Cup Champion Bobby Labonte (pictured) and former Raybestos Rookie of the Year Tony Stewart.

Why now the reunion on the track between the brothers?

"I don't know...I guess Darlington is one of my favourite tracks," said J.D. "I have experience there and I've tested there-it was also the scene of my first Busch Series race a couple of years ago. For me, this is just about the fun of driving there. Turn one is such a turn down into that corner and then you're right up against the wall-it's like a roller coaster," he added.

Don't think for a moment that these brothers won't be aware of each other on the famed 1.33 mile track. They have a way of keeping score.

"For the record, I am still leading overall in our head-to-head competition," J.D. joked. "This goes way back...all the way to our late model days," he added.

In summation, it looks like Sunday's action will be yet another chapter of that pesky competitiveness known as the "Sibling Rivalry".
