The provisional entry lists have been released for the upcoming triple-header at EchoPark Speedway in Atlanta, Georgia.
The Cup race will feature 38 entries with the open teams of BJ McLeod (#78 Live Fast) and JJ Yeley (#44 NY Racing Team) joining the 36 chartered entries. Casey Mears and the No. 66 team originally planned to compete, but after damage suffered in Daytona Speedweek, they have withdrawn.
There will be one full-time Cup driver in the NASCAR O'Reilly Series, and that's Ross Chastain. He will be driving the #32 Jordan Anderson Racing Chevrolet for the first time in his career. There will be 39 cars for 38 spots in that race.
The Truck race will feature 36 entries, including several Cup stars: Kyle Busch (#7 Spire), Ty Dillon (#25 Kaulig), Ricky Stenhouse Jr. (#45 Niece), John-Hunter Nemechek (#62 Halmar-Friesen), and Carson Hocevar (#77 Spire). Additionally, reigning Truck Series champion Corey Heim is back on the grid with TRICON, driving the #1 entry.
