Hamlin, who was set to start his No. 11 Joe Gibbs Racing Toyota from the pole position, will start out back because of unapproved adjustments before the 267-lap, 400.5-mile race at the 1.5-mile South Florida track. Alex Bowman, driver of the No. 48 Hendrick Motorsports Chevrolet, and Corey LaJoie, driver of the No. 7 Spire Motorsports Chevrolet, will also drop to the rear for unapproved adjustments. Bowman was slated to start 13th, while LaJoie was in the 25th starting position.
A fourth car, the No. 15 Rick Ware Racing Chevrolet driven by James Davison, will also start at the rear for failing pre-race inspection twice. Davison was originally supposed to start 29th.
