Fort Worth, Texas ? It took Greg Biffle a little while to overcome the mental and physical discomfort from a crash in practice at Texas Motor Speedway.

It took hardly any time at all for him to make the rest of the field feel bad in Sunday’s Samsung/Radio Shack 500.

“I was sore when I went to bed, sore when I woke up, and I’m still sore,” said Biffle, who ran over debris on the track during a Nextel Cup practice Saturday, cutting down the right front tire and slamming into the wall on the fast 1 1/2-mile oval.

“It’s been in the back of my head thinking about it ever since, but it hasn’t slowed me down.”

After charging from the rear of the 43-car field in a backup car, the Roush Racing driver was overpowering Sunday, leading 219 of 334 laps to grab his second victory of the season and the fifth of his career.

“As soon as I caught my breath after the crash, I told the guys I was OK and to get the backup out,” Biffle said. “They did an incredible job of getting that car ready. I want to thank all the guys from the other (Roush) teams. There were probably five or six different color uniforms over there working on getting that car ready.”

Fortunately for Biffle, his backup No. 16 Ford was the same car in which he won earlier this season in California, so he wasn’t too concerned about being competitive.

He picked off cars two and three at a time early in the race, moving all the way to 15th by lap 26. He took the lead for the first time on lap 87.

Biffle kept pulling away from the rest of the pack, but the race was slowed by 11 caution flags, keeping him from turning it into a rout.

The leaders made their final pit stops on lap 298 after Tony Stewart’s engine blew, setting his Chevrolet on fire and bringing out the yellow flag. Stewart sustained minor burns to his right leg and right arm and was treated and released at the infield medical center.
