NASCAR Cup Series driver Alex Bowman will miss his second straight race on Sunday while battling vertigo.
Hendrick Motorsports announced on Wednesday that Justin Allgaier will pilot the No 48 Chevrolet at Las Vegas Motor Speedway.
Anthony Alfredo replaced Bowman last Sunday at Phoenix Raceway and finished 33rd.
"Alex continues to work closely with doctors toward being medically cleared, but he's still experiencing some lingering symptoms," Hendrick Motorsports president and general manager Jeff Andrews said in a team statement.
"He's put a lot into the recovery process, and we will continue to support him every step of the way. Our priority remains making sure Alex is fully ready before returning to the race car."
Bowman, 32, became ill during the March 1 race at Circuit of The Americas in Austin, Texas, and was replaced by Myatt Snider after completing 71 of the 95 laps.
Bowman, an eight-time winner in the Cup Series, was diagnosed with vertigo. The condition, usually caused by an inner-ear issue, can produce sensations of dizziness and loss of balance.
Bowman missed five races in 2022 with a concussion and sat out three races in 2023 with a broken back. His most recent win came at the Chicago Street Course in July 2024.
Allgaier, 39, is coming off his 29th career victory in the NASCAR O'Reilly Auto Parts Series last Saturday in Phoenix.
He has 84 career starts in the Cup Series, most recently at the 2026 Daytona 500 with JR Motorsports.
