Tempers flare on the track in Texas for some NASCAR drivers.
FOX News Radio's Steve Rappoport reports:
Jimmie Johnson won the Texas 500, but the real action was set in motion with two laps to go.
The rivals made contact once again when Gordon angrily confronted Keselowski in pit row after the race.
A brawl quickly erupted with crew members from both sides throwing punches. Gordon cut his lip in the melee.
(Gordon) "The way he races -- I don't know how he's ever won a championship."
While a bruised Keselowski offered no apologies.
(Keselowski) "I'm still here fighting. It's not going to change the way I race."
NASCAR officials will review the incident and could issue penalties this week.
