Sprint Cup Series driver Denny Hamlin's crew work on his car before the NASCAR Quicken Loans 400 auto race at Michigan International Speedway Sunday, June 16, 2013, in Brooklyn, Mich. Hamlin's Toyota has changed its paint scheme for Sunday's race to the one that was used when Jason Leffler drove the car in 2005. The tribute paint scheme was Hamlin's idea and approved by Joe Gibbs Racing and sponsor FedEx following Leffler's death Wednesday in an accident at a dirt track in New Jersey. (AP Photo/Carlos Osorio)
