There have been two catuions thus far in the Coke Zero 400, and the top-two drivers in February's Daytona 500 have both been eliminated from contention. First, it was Trevor Bayne, the Daytona 500 winner, who slammed the turn one wall after contact with Brad Keselowski.
Contact between teammates Greg Biffle and Carl Edwards sent Edwards sliding into the Inside frontstretch wall, doing significant damage from the right-rear corner of his Ford. Biffle smacked the wall as well, doing damage to his car.
Edwards came into the day with the Sprint Cup point lead, but is likely to give away a large chunk of that advantage depending on what happens in the remainder of tonight's event.
Familiar drafting partners Kurt Busch and Regan Smith were the pair leading the race as Edwards and Biffle crashed trying to overtake them. Mark Martin and Jeff Gordon, along with Jimmie Johnson and Dale Earnhardt Jr., have been other drafting tandems to spend time at the front of the field.
