One day after deciding the starting grid for Sunday's Dickies 500 at the Texas Motorspeedway, the Sprint Cup cars were back on track for their second practice session.
Things got interesting.
Greg Biffle, two-time Chase winner, was the fastest with a lap of 184.78 mph. The two man battling for the championship, Carl Edwards and Jimmie Johnson were second and third fastest with laps of 184.45 and 184.42 mph.
Pole sitter Jeff Gordon was eight quick with a lap of 182.34 mph.
Then things got hairy.
Eight minutes into practice Robby Gordon slammed the wall in turn one after he said he felt something break in his car. Practice would be delayed for clean-up.
Upon resuming Tony Stewart blew a right rear tire going down the backstretch.
Travis Kvapil was among others whose cars slid into the wall. Because of the incidents practice was extended for 10 minutes.
No word on anyone having to use back-up cars.
The final practice session, Happy Hour, is now underway.
Who will be happy in Texas after it's done?
Update: Both Tony Stewart and Robby Gordon will have to go to their backup cars. The result is both having to start in the back of the field on Sunday.
