A multi-car wreck in Gatorade Duel practice that involved Mike Bliss, Joey Logano, Jimmie Johnson all of which need to go to a backup car and will start in the back of their Duel race.  Denny Hamlin was rear-ended by the 48, but did not need their backup car.  Jimmie Johnson’s crew sent their wrecked 48 machine back to Charlotte for repairs, and it will return to Daytona as a back up.
