Brad Keselowski faces a six-point penalty for his car being too low during postrace inspection at Dover.
Earlier this year, Martin Truex Jr. was docked six points for his car being too low. Keselowski likely faces a similar penalty.
Keselowski finished fifth and his car was automatically checked during postracet. He likely will learn of the penalty Tuesday. A six-point penalty would drop him from eighth to 10th in the standings with an eight-point edge on 11th-place Jeff Gordon.
Although Keselowski crew chief Paul Wolfe is on probation for illegal suspension pieces from earlier this year, typically NASCAR does not factor probation into penalties unless the infractions are similar. Wolfe just returned from a three-week suspension Sunday at Dover.
Keselowski was docked 25 points earlier this year for the illegal suspension parts.
