Trackhouse Racing has lost its appeal of sanctions imposed earlier this week by NASCAR for being involved in what was considered race manipulation at Martinsville Speedway.

NASCAR awarded the team and driver Ross Chastain 50 points, fined them $100,000 each and imposed one-race suspensions on crew chief Phil Surgen, observer Brandon McReynolds and team principal Tony Lunders. Trackhouse was one of three teams penalized, the others being Richard Childress Racing and 23XI Racing.

The three-person National Motorsports Appeals Committee was Kelly Housby, Lyn St. James and Steve York. A statement released by the panel explains: “We believe that in the best interest of racing and to protect the integrity of the sport, it was appropriate to uphold and affirm NASCAR’s decision regarding NASCAR Rule 4.4, attempting to manipulate the outcome of the race.”

Trackhouse Racing will not make a final call.

“We respect the decision and will put the matter behind us,” a team statement said. “We look forward to a great championship weekend.”

The organization was penalized for helping fellow Chevrolet driver William Byron in the closing laps of the playoff race at Martinsville. Byron was looking to advance in Championship 4 and is ahead of Chastain and Austin Dillon. The two drivers never attempted to pass Byron and at times raced side by side, blocking the track for others. There was also radio communication about the situation.

Richard Childress Racing has withdrawn its appeal. 23XI Racing chose not to appeal.
