Joey Logano and Brad Keselowski will both be without their crew chiefs at Dover.

Joey Logano’s crew chief is suspended due to a lugnut missing penalty following Darlington. He’ll be suspended next week too. Jonathan Hassler will serve as his crew chief. He’s a Penske Racing engineer. Hassler was Matt DiBenedetto’s fill-in crew chief at Martinsville (Finished 12th).

Brad Keselowski’s crew chief is out due to health pre-cautions a second week. Grant Hutchens who was his crew chief last week at Darlington will be sitting on his pitbox again.
