NASCAR Xfinity Series driver Darrell Wallace Jr. was fined $15,000 by NASCAR on Wednesday for his actions following the Subway Firecracker 250 at Daytona International Speedway.

Wallace was penalized for violating Sections 12.1; 12.8 a, and 12.8.1 b, which refer to NASCAR member conduct, including disparaging the sport and/or NASCAR's leadership and verbal abuse of a NASCAR Official, media members, or fans.  The penalty for an infraction of this rule can result in a fine of $5,000 to $25,000 and/or probation.

The driver of the No. 6 Ford Mustang for Roush Fenway Racing was critical of NASCAR officials after last week's race. Wallace tweeted "Got the muppets up there officiating tonight! Never know how to react under pressure… Whatta joke."

Wallace currently sits ninth in the NASCAR Xfinity Series standings, 105 points behind leader Daniel Suarez.
