The race went green again on lap 37 but almost immediately there was a multiple-car accident as drivers tried to make the most of the overtaking opportunities the bunched-up field presented. Brian Vickers got a sustained hard shove from behind by Tony Stewart into turn 11 which propelled him down the track on locked-up tyres for a skid of some 20 feet, collecting other cars along the way - including inflicting serious damage onto the side of the #88 of Dale Earnhardt Jr. which holed his radiator and led to the engine blowing.
"I'm not a big fan of the place, but maybe one of these days," Earnhardt said, who lost three hard-won places in the Sprint Cup standings as a result of his early retirement from the race.
Stewart was unapologetic about the crash and didn't deny that it had been intentional. "I've been complaining about the way guys have been racing all year," Stewart said. "I like Brian. I'm not holding it against him at all. I don't care if it was Ryan Newman; I would have dumped him, too. If they want to block, that's what is going to happen to them every time for the rest of my career."
Vickers, however, refuted the accusation that he had been blocking and instead pointed to an accident that was unfolding ahead of him, in which Kyle Busch's attempt to overtake Juan Montoya had ended up with the #18 in the grass and spraying up the dirt.
"I wasn't blocking him. That may have been his perception from where he was sitting, but the #18 went off the race track in front of me," Vickers said. "He was going off in the dirt and then coming back in front of me on the race track, and I was trying to avoid him. The cars in front of me were slow. I was inside of the guy in front of me ... I think when [Stewart] sees the replay and he realises why I went low - if he looks at it out of my front windshield - he'll realise it had nothing to do with him. It had to do with the #18 almost wrecking me, and a couple of other guys running slow up top."
Both cars were able to continue, although with some degree of bodywork damage - Vickers's #83 looking particularly shopworn.
The brief green flag running had been long enough to allow Kurt Busch to pass Denny Hamlin for the lead, so it was the #22 who led the field round for the next restart on lap 42, followed by Hamlin, Martin Truex Jr. and David Gilliland - who was quickly passed for position by Allmendinger, who then went three-wide through turn 11 for second place with Hamlin and Truex. It couldn't end well, and it didn't: Truex was sent spinning and Hamlin, while Allmendinger slipped through fo the position and Hamlin himself found his #11 damaged by Allmendinger's play. There was no immediate caution for the contact, but one followed on lap 46 for debris in that same area.
Kurt Busch led the field back to racing on lap 51, only to lose the lead when Clint Bowyer made a nice dive in front out of turn 2. Behind them, Tony Stewart got past Jimmie Johnson for third with Brad Keselowski behind them in fifth.
Despite Robby Gordon making contact with the barrier after contact with Joey Logano - who just seemed to lose patience with the #7 - there was no new immediate yellow flag, and next time around Kurt Busch was able to pass Bowyer to reclaim the lead at turn 11; over the ensuing laps, Tony Stewart was able to pass Bowyer to take up the chase and he was starting to close in when the fourth caution of the afternoon came out for Bobby Labonte hitting the wall with a little assist from Michael McDowell and leaving fluid on the front stretch of the track that took a lengthy five lap caution to properly clear up before racing could resume.
That allowed a number of cars to come into the pits, including Denny Hamlin whose car was still struggling with damage from that earlier contact with Truex and Allmendinger. Jamie McMurray had already been into the pits just before the caution came out because of a flat tyre, and while he reported that the car was "really good right now", it had blown the team's two-stop strategy that the leader Kurt Busch was still on line to achieve especially after this length mid-race caution.
The green came out on lap 65 with Busch leading Tony Stewart, Clint Bowyer, Martin Truex Jr. and Jimmie Johnson - but Kurt's brother Kyle was swiftly up into fourth place, Further back there was contact between Matt Kenseth and Joey Logano that left Kenseth pointing in the wrong direction and having to wait for everyone to stream past him before he could resume in last place on the lead lap, which meant there was no return to caution.
