Kevin Harvick, who needs a strong finish on Sunday to climb out of the Chase cellar, brushed the outside wall ever so slightly in Saturday’s final NASCAR Sprint Cup Series practice at Kansas Speedway. But the No. 4 car sustained some appreciable damage after recording the fastest ten-lap average in the session at 183.740 mph.

Kurt Busch, Harvick’s Stewart-Haas Racing teammate, wasn’t as fortunate. After posting the third fastest single lap in happy Hour (185.797 mph), Busch blew his right front tire on the final lap of his closing run and dug the front of his No. 41 Chevrolet into the infield grass. Busch had to go to a backup car and will start Sunday’s Hollywood Casino 400 with no practice laps in the backup.

Pole winner Matt Kenseth was fastest in final practice at 186.361, an indication his car is equally stout in race trim.
