Seven-time NASCAR Cup Series champion and four-time Coke 600 winner Jimmie Johnson will be one of those open entries, driving the No. 84 Legacy Motor Club Toyota. It will also be Johnson's 700th career start.
Trackhouse Racing will enter a fourth car with rising star Connor Zilisch driving the No. 87 Chevrolet, making his second career start in the Cup Series but his first on an oval. Zilisch skipped the most recent Xfinity race at Kansas due to a back injury, but he has been cleared to return to competition this weekend.
Garage 66. (formerly MBM Motorsports) will enter the No. 66 Ford Mustang with Josh Bilicki as the driver while NY Racing Team will enter the No. 44 Chevrolet. No driver has been officially announced for the NY Racing Team entry, but it's likely to be J.J. Yeley.
There are also 40 entries for the NASCAR Xfinity race, which will feature the following Cup stars: William Byron, Austin Dillon, and Chase Briscoe. Of note, Katherine Legge will also be participating after skipping this year's Indy 500 in favor of gaining more stock car experience.
There are 34 entries for the Truck Series, bringing the total to 114 for the three national divisions. Kyle Busch and Ross Chastain are the only full-time Cup drivers in the field, but B.J. McLeod will also be taking part after putting a deal together with Spire Motorsport.
