Martinsville Speedway is scheduled to host the first of its two annual NASCAR Cup Series races this coming Sunday afternoon, and given the fact that it is once again on the schedule as the cutoff race just before the Championship 4 in late October, Sunday's Cook Out 400 is considered one of the regular season's most important events.
The race is scheduled to be a 400-lap race around the four-turn, 0.526-mile (0.847-kilometer) Ridgeway, Virginia oval, and there are 38 cars on the entry list.
All things considered, three changes have been made to the entry list since this past Sunday afternoon's race at Homestead-Miami Speedway.

Martinsville entry list: 3 changes
First and foremost, the No. 44 NY Racing Chevrolet is not on the entry list after J.J. Yeley made his second start in the entry at Homestead and finished in 35th place.
But two additions have been made, both by teams that have not yet successfully qualified for an event this year but are locked in this weekend, even as non-chartered (open) teams, since the entry list features fewer than 40 cars.
Team AmeriVet, which tried but failed to qualify for the Cook Out Clash preseason exhibition race at Bowman Gray Stadium, are set to field the No. 50 Chevrolet for Burt Myers, who was their driver at Bowman Gray back in early February.
Then there is Garage 66, the team formerly known as MBM Motorsports. After failing to qualify for the Clash with Garrett Smithley behind the wheel of the No. 66 Ford and after failing to qualify for the official season-opening Daytona 500 with Chandler Smith behind the wheel after NASCAR ruled that Mike Wallace was ineligible to compete, they too are set to make their first start of the year.
Casey Mears has not competed in a Cup Series race since the 2019 Daytona 500, which is his only race since he stopped competing full-time at the end of the 2016 season. His 2025 Cup return was not on the bingo cards of many fans, but after an absence of more than six years, he is set to make his Next Gen debut at "The Paperclip".
Fox Sports 1 is set to provide live coverage of the Cook Out 400 from Martinsville Speedway beginning at 3:00 p.m. ET this Sunday, March 30.
