Gragson, 25, has been suspended by the team and will not be racing this weekend. The 2022 NASCAR Xfinity Series championship runner-up is a rookie in the Cup Series this year, and currently sits 33rd in points and second in the rookie ranks.
Xfinity Series regular Josh Berry will drive the #42 car this weekend at Michigan. Berry has made several starts this year, filling in for Chase Elliott and Alex Bowman at Hendrick Motorsports while they were both out injured. He will be a full-time Cup driver next year, taking over the #4 Stewart-Haas Racing Ford after Kevin Harvick retires.
Legacy Motor Club, co-owned by Jimmie Johnson and Maury Gallagher, released the following statement, but did not indicate the specific reason for the suspension: "We have made the decision to suspend Noah Gragson effective immediately regarding his actions that do not represent the values of our team. Josh Berry will drive the #42 entry for this weekend's NASCAR Cup Series race at Michigan."
NASCAR has not taken any disciplinary action against Gragson at this time.
