Justin Allgaier was involved in the NASCAR Xfinity Phoenix practice accident

Brennan Poole, driving the No. 44 Alpha Prime Racing Chevrolet, had an issue in Turns 1 and 2 and apparently put some fluid on the track. Allgaier, Brandon Jones and Aric Almirola ran through the slick surface, slid to the wall and made solid contact.

Several other cars were damaged before the red flag was cancelled, but Allgaier was the only 4th Championship driver involved in the incident. Almirola and the No. 20 Joe Gibbs Racing team are still in the running for the owner's points title.

The No. 7 JR Motorsports Chevrolet team was already unloading the backup car for Allgaier with more than half an hour left in practice, meaning he will start at the back of the field on Saturday. Allgaier expressed his anger by hitting the pits after getting out of the car in the garage, then told NBC that the damaged car was the best car he ever had in Phoenix.
