Earnhardt Jr. and Hamlin pulling double-duty at Las Vegas

No Kevin Harvick in Xfinity Series race at Las Vegas

Dale Earnhardt Jr., Denny Hamlin and nine others will be trying to pull off a feat accomplished only twice in Las Vegas Motor Speedway history - sweep both the Sprint Cup and Xfinity Series races at LVMS.

Earnhardt, Hamlin, Aric Almirola, Austin Dillon and Las Vegas native Brendan Gaughan highlight the drivers pulling double duty this weekend. These five make up part of the 48 cars entered in Sunday's Kobalt 400 NASCAR Sprint Cup Series race as well as the 42 drivers entered in Saturday's Boyd Gaming 300 NASCAR Xfinity Series race. Other racers pulling double duty are Ryan Blaney, Landon Cassill, J.J. Yeley, Mike Bliss, Ty Dillon and Regan Smith. Smith us subbing for suspended Kurt Busch in the Sprint Cup event.

If one of these drivers pulls off the sweep he would join Jeff Burton in 1999 and Brad Keselowski last year as the only drivers to sweep the weekend.
