NASCAR warned six Sprint Cup teams on Wednesday for infractions occurring during the Dover race weekend, including the Chase-contending teams of Kurt Busch and Martin Truex Jr.
Busch’s No. 41 team was posted for rear bumper tubing found during pre-race inspection. The No. 14 team of Busch’s teammate and owner Tony Stewart was warned for the same infraction.
The No. 78 of Truex, the No. 46 of Michael Annett, the No. 23 of Jeb Burton and the No. 6 of Trevor Bayne were also given warnings for failing pre-race tech too many times.
For Truex, it was the second penalty of the day. NASCAR placed his crew chief Cole Pearn on probation through Dec. 31 after the team was found to have illegally modified the right-rear quarterpanel between pre-race inspection and the start of the race.
