Darrell “Bubba” Wallace Jr. took to Twitter on Thursday to apologize for his actions following Saturday night’s Xfinity Series race at Kentucky Speedway.
Wallace and Brian Scott had gotten into each other in the race, prompting Scott to come looking for Wallace after the checkered flag.
Scott confronted Wallace first while the latter was still in his race car, and then again a few moments later on pit road.
The confrontation was verbal, although the two were physically separated from each other by a NASCAR official after Wallace climbed from his car.
“I reacted unprofessionally and I’m not proud of it,” Wallace said.
