CONCORD, N.C. — Rain washed out all track activity Friday at Charlotte Motor Speedway, which will now try to cram it’s All-Star weekend into one day.

Steady showers forced NASCAR to call off the scheduled Sprint Showdown, a race that will send five drivers not already qualified for the All-Star race into the main event. The Truck Series race also was postponed.

Both events were rescheduled for early Saturday, with the $1 million All-Star race still scheduled to go off in the evening.

The Sprint Showdown is divided into three segments, and the winner of each segment will advance into the All-Star race. Two more drivers will get into the All-Star race on a fan vote.

All drivers who won a race last year are eligible, as well as past All-Star race winners Tony Stewart, Jamie McMurray, Ryan Newman and Kasey Kahne.

The All-Star race will be 113 laps divided into three segments. Drivers must make at least a two-tire pit stop under green during the first 50 laps, then must do a minimum two-tire pit stop during the first break. The second segment will also be 50 laps and require a minimum two-tire pit stop under green before the 35th lap. There will then be a draw to determine whether the first nine, 10 or 11 cars will have to do a four-tire pit stop during the break while the remaining cars will not be allowed to pit.

The final 13-lap segment will count only green-flag laps as drivers with fresh tires try to gain the lead from the drivers on old tires.

INDYCAR: Team Penske’s Will Power pushed Chevrolet to the top of the Indianapolis 500’s practice speed chart with a fast lap of 232.672 mph.

Another Chevy driver, Josef Newgarden of Ed Carpenter Racing, was second at 232.344.
