Kasey Kahne's streak of seven top-10 finishes will likely not be extended to eight today. The Hendrick Motorsports driver blew the right-front tire entering the tunnel turn and slapped the wall on lap 136 to draw the sixth yellow flag of the race. Kahne's tire likely went down as a result of contact made with Denny Hamlin as they raced for position in the third turn on the most-recent restart.
The yellow flag means the race will restart with fewer than 25 laps remaining in the Pocono 400. The fuel-mileage game is in full force, as leaders Joey Logano, Mark Martin, Denny Hamlin, Tony Stewart, and Matt Kenseth are trying to make it to the finish without pitting. Dale Earnhardt Jr., who has had one of the fastest cars all day long, pitted to make sure he will be able to make it to the finish on fuel.
Amid all the fuel discussion, championship leader Greg Biffle's day has gone south. He dropped a cylinder on his Roush-Fenway Racing Ford and will almost certainly lose the lead to Kenseth or Earnhardt Jr., with whichever one that finishes better in the race taking over the top spot.
