IndyCar has confirmed the postponement of the Firestone 600 after the ninth race of the season was stopped after 71 laps on Saturday due to heavy rain.
Instead, the suspended race will take place on August 27 as a night race at the Texas Motor Speedway (TMS), when the 248-lap event finally concludes in two months after the weather did not improve on Sunday.
"We certainly want to come back and have a full race for the fans here in Texas," said Jay Frye, IndyCar president of competition and operations.
"The people at TMS do a great job, so what we will do, per our rulebook, is start the race from where we stopped. So we will come back and start the race from that point.
"This is unique. It hasn't happened for a little while, but there are a lot of unique things here and we'll look forward to coming back August 27."
The last IndyCar Series race to start one day and finish on another came at Sao Paulo, Brazil, in 2011.
