A NASCAR spokesman confirmed Friday evening that the 19-year-old native of Wallkill, N.Y., has been suspended for actions detrimental to stock car racing, including a violation of the sport's code of conduct.
Dippel was scheduled to compete in Sunday's Chevrolet Silverado 250 at Canadian Tire Motorsport Park in Bowmanville, Ontario.
Young's Motorsports announced Saturday morning that two-time NASCAR Pinty's Series champion D.J. Kennington will drive the No. 02 Chevrolet in place of Dippel this weekend.
"We understand NASCAR's position regarding Young's Motorsports driver Tyler Dippel and accept their decision. Our team was notified of the decision on Thursday, Aug. 22. We respect the NASCAR policy as well as the process that NASCAR has gone through for this matter," a statement from Young's Motorsports said.
"Young's Motorsports is disappointed with the situation and will evaluate its future course of action in regards to Dippel. We are finalizing our plans for the race at the Las Vegas Motor Speedway and will announce those details as soon as they are complete."
Dippel missed the playoffs this season but is currently 13th in the series standings with one top-five an three top-10 finishes. He finished a career-best third at Michigan earlier this month.
