William Sawalich will drive the No. 5 Toyota this weekend at Texas Motor Speedway, replacing Chase Briscoe in the Nascar Truck Series ride. It is a fresh assignment for Sawalich, who has never before run a Truck Series race at Texas.
The 19-year-old arrives with momentum after earning his first career O'Reilly Series victory at Rockingham Speedway earlier this month. He also has one previous Truck Series outing this year, finishing 10th at Darlington Raceway in March and making that start in the No. 1 Toyota.
Sawalich has made all 22 of his career Truck Series starts in the No. 1 entry since his debut in 2023. His best finish in the series is sixth place, a result he recorded at Lucas Oil Indianapolis Raceway Park in 2023, and he owns five career top 10 finishes overall.
The Texas race gives him a new seat but not an unfamiliar level of pressure. Sawalich finished 13th there as a rookie in the O'Reilly Series in 2025, and this week he will try to translate that experience into a stronger showing in a different machine and a different class.
Briscoe, meanwhile, is out of the No. 5 after finishing 14th in his first Truck Series start in three years at Bristol Motor Speedway. That race was his first in the series since 2023, and his 19th-place finish at Kansas Speedway in 2021 marked his first non-dirt Truck Series start since then. More Truck Series starts for Briscoe this season have not been ruled out, but none have been confirmed beyond Texas.
The move underscores how quickly opportunities can shift in the NASCAR Truck Series. For Sawalich, Texas is a chance to show he can do more than settle into the role he has held since 2023; for Briscoe, it is another pause in a comeback that has not yet settled into a full schedule.
