BRISTOL, Tenn. -- The beating and banging typically associated with Bristol Motor Speedway will become painfully evident to Greg Biffle this weekend.

The Roush Fenway Racing driver will compete on the physical short track with bruised ribs he suffered in a fall on a boat dock Tuesday night. The injury led Biffle to turn his scheduled Nationwide Series ride over to teammate Matt Kenseth.

“

I'm disappointed, trust me, that I'm not running the Nationwide race.

"Remarkably, I cannot believe how much better I feel in three days. I did it Tuesday night, and I was really hurting Tuesday night. I felt a fair amount better by the end of the day Wednesday, and yesterday I was up and doing all kinds of stuff, stretching and getting ready to go, so I feel pretty good now," said Biffle, 10th in Sprint Cup points.

"The reason why I'm just focusing on the Cup race is, you're bruised, and if you get in a wreck in the Nationwide car, you blow a tire, you know how easy it is to get in a chain-reaction crash here. I'm thinking, why be even more sore for Sunday if something happened? Matt and I were fighting over this race to see who was going to get to run it, so we're just going to swap Daytona or something like that so we keep the same amount of races. But I'm disappointed, trust me, that I'm not running the Nationwide race."

Biffle said he went to the Roush shop Thursday and sat in his Martinsville car -- his Bristol car was already on its way to the race track -- to see how he felt in the vehicle. "I drove over there in my truck, and I actually feel better sitting in that [race car] seat because it's hard foam and it's molded," he said. "It doesn't create any pressure points."

Biffle suffered the injury trying to jump from a boat onto the dock.

"It was about 11:30, so there was a little bit of dew in the air and the platform must have been wet, and when I jumped over it just shot my foot out from underneath me. It turned me around backward and put me right on my side and on my back on the edge of the boat," he said. "It's not a normal boat. It's got a sharp edge on it because it has a platform on the front. So it's just one of those freak, stupid accidents where you take a fall and you have no way to stop it or brace it or grab, because I was over top of water. You're going to land on your ribs with all your weight, plus you jumped on top of it, so it was a stupid deal. If I had to do it over, I didn't do anything out of the ordinary. Everybody's jumped onto a boat before, but I just lost my footing."
