Tough break for Dinger Nation! After his Charlotte heroics, A.J. Allmendinger was looking to leap over the playoff cut at Nashville, but a post-qualifying splitter change landed the No. 16 team in hot water.

Do you think this crackdown was fair, or did NASCAR go too far? Let’s hear your takes! #NASCAR #Allmendinger #CrackerBarrel400 #Sports
