Rain limits All-Star racers' practice time

Five laps were the most a driver got during practice at Charlotte Motor Speedway.

The threat of rain saw NASCAR make the decision to combine the practice sessions for the Monster Energy All-Star Race drivers and those competing in the Open. But the session was interrupted twice for rain and then canceled.

Kevin Harvick was fastest at 170.406mph and Stewart-Haas Racing teammate Kurt Busch was second quick at 169.502mph.

The rest of the top five were Denny Hamlin (169.428mph), Ricky Stenhouse Jr. (169.412mph) and Clint Bowyer (169.030mph). All five of these drivers are already locked into the All-Star Race.

Sixth fastest was Aric Almirola (168.629mph) with Darrell Wallace Jr. seventh fastest at (168.219mph). Almirola and Wallace will be in the Open.

Completing the top 10 were All-Star Race drivers Kyle Larson (167.999mph), Jimmie Johnson (167.629mph) and Joey Logano (166.862mph).

Johnson was the only driver who completed five laps in the session while four other drivers ran four circuits. There were 15 drivers who did not get in a lap at speed.

NASCAR has already made the decision to cancel Open qualifying but remains hopeful that All-Star Race qualifying will take place at 6:35 p.m. ET.
