NASCAR's indefinite suspension of Kurt Busch was upheld Saturday, despite an appeal submitted by the driver days before the Daytona 500 race, NASCAR announced.
The suspension was handed down a day after a Delaware judge found Busch strangled his ex-girlfriend, Patricia Driscoll, and smashed her head into a wall.
Busch's appeal was heard, and ultimately denied, by a three-member panel.
According to NASCAR, he can make one last appeal on the decision to the Final Appeals Officer, who has said he would hear the appeal this evening if Busch requests it.
Meanwhile, the Dover Police Department in Delaware has turned the case over to the county's attorney general's office, which is considering the case.
