NASCAR has confirmed that Ross Chastain will make a notable racing series switch this weekend at Iowa Speedway, competing in both the Cup and Xfinity Series events. Following a tense race at Indianapolis Motor Speedway, Chastain is set to drive the No. 9 JR Motorsports Chevrolet in the Xfinity race on Saturday, while continuing his regular role in the No. 1 Trackhouse Racing Chevrolet in the Cup Series.
Chastain’s Xfinity Series Record So Far in 2024
Chastain, 32, has participated in four Xfinity Series races this season, all with Dale Earnhardt Jr.’s JR Motorsports team in the No. 9 car. Although he has yet to secure a win this year, his best performance came with a fourth-place finish at Darlington. He also finished fifth at Nashville, eighth at the Circuit of the Americas, and 38th at Dover.

Chastain will not be alone among Cup drivers racing in the Xfinity Series this weekend. Austin Dillon is set to take the wheel of the No. 21 Richard Childress Racing Chevrolet, replacing Austin Hill, who has been handed a one-race suspension following a collision with Aric Almirola at Indianapolis.
