Michael Annett, a driver in the NASCAR Nationwide Series, will be out indefinitely after suffering a broken sternum in Saturday's race at Daytona International Speedway, his team said Tuesday.
Annett, 26, was scheduled to have surgery after doctors in North Carolina determined he had fractured and dislocated his sternum, or breastbone, Richard Petty Motorsports said.
Aric Almirola was tapped to drive Annett's No. 43 Ford at the Nationwide Series race this Saturday at Phoenix International Raceway in Arizona.
Annett was part of a multicar crash near the end of last Saturday's race, with Annett's car slamming head-on into Daytona's outside wall.
