Bad race aside, Biffle wants to re-sign with Roush Fenway Racing

CHARLOTTE, N.C. -- Greg Biffle said on Thursday he remains 100 percent committed to re-signing with Roush Fenway Racing.

Biffle's commitment to signing a new deal was questioned after he criticized his team following Saturday night's race at Darlington Raceway. He had the fastest car the first half of the race, but fell back because of a loose wheel and then was sidelined when the timing belt broke.

"That had nothing to do with my contract," he said before the All-Star Pit Crew Challenge at the Charlotte Bobcats Arena. "I was mad my stuff was broke."

Biffle said negotiations are continuing and he hopes to finish a deal by mid-summer.

"That is my focus," he said. "My focus hasn't changed."
