NASCAR driver Cole Custer was fined $100,000 and lost 50 points after officials determined his actions helped teammate Chase Briscoe get ahead on the final lap of last weekend’s Cup Playoffs.

The race took place at Charlotte Motor Speedway and officials say Custer deliberately blocked other competitors so Briscoe could advance. Officials also considered removing Briscoe from the playoffs but they could not be certain he was part of the scheme and could not penalize him for Custer’s actions, according to Autoweek. Crew chief Michael Shiplett was also fined.

Wow. NASCAR fines Cole Custer $100,000 and docks him 50 points, then fines crew chief Mike Shiplett $100,000 and indefinitely suspends him. This is related to slowing down with teammate Chase Briscoe trying to get points at the end of the Roval.

Video evidence and radio transmissions were used to determine that Custer “intentionally impeded” other drivers in an attempt to aid Briscoe to the finish line, according to Autoweek. NASCAR officials stopped short of using the term “Finish Fixing,” but Custer’s actions meet the definition of the term, the outlet reported.

NASCAR drivers Austin Dillon, Erik Jones, and Briscoe were racing for position on the backstretch and came behind Custer’s car. He allegedly slowed down rather dramatically and interfered with Dillon’s line, forcing him to slow as he entered the backstretch chicane, according to Autoweek.

Briscoe used the inside advantage and passed Custer, Dillon, and Jones, immediately gaining points and advancing by three positions, according to the outlet. (RELATED: NASCAR Legend Jimmie Johnson Announces Retirement From Full-Time Racing)
