Austin Dillon, the current Nationwide series points leader will racing in both the Nationwide and Sprint Cup race, filling in for Tony Stewart -- still on the mend after breaking his leg.

Michael Waltrip Racing now has Aaron's as the primary sponsor for the No. 55 car for two full seasons starting next year, and driver Brian Vickers is promoted from part-time to full-time status. And for Vickers...
