Fox Sports reported Wednesday that Whitney Scott, the wife of Boise driver Brian Scott, and fellow driver Darrell Wallace Jr. are on probation through the end of the year for their roles in a post-race altercation following last Saturday’s Xfinity Series race at Kentucky Speedway. Brian Allen, the motorhome driver for Scott, has been indefinitely suspended from NASCAR. Angry about contact with Wallace that loosened his right-rear wheel late in Saturday’s race, Scott approached Wallace twice on pit road after the race to express his displeasure. From there, the two engaged in a profanity-laced shouting match. Scott later used Twitter to accuse Wallace of calling his wife a disparaging name.
