Jimmie Johnson has spun off turn four to draw the sixth caution in the race and the first in nearly 100 laps at lap 221.
Carl Edwards had grabbed the lead during the green-flag stretch as Kyle Busch was forced to pit road for a loose rear wheel. Busch had led a race-high 78 laps in his pursuit of his second-straight win and a weekend sweep. He had a lead of more than two and a half seconds after the pit stops, but he has now fallen a lap down in 23rd place affter the green flag pit stop.
Johnson's trouble began on lap 83 when he spun off the front bumper of Juan Pablo Montoya, who has been a controversey magnet in recent weeks. The five-time defending series champion avoided contact with the wall, but lost significant track position with flat tires. He was running within the top-15 when he spun this time, but was again able to keep his Chevrolet from sustaining damage.
With 225 laps complete, the top five are Edwards, Kevin Harvick, Kasey Kahne, Tony Stewart, and Jeff Gordon.
