The greater Indianapolis area's severe weather on Sunday presented a number of unknowns and, in the end, a "worst-case scenario" for Kyle Larson's attempt to run "The Double."
The driver for Hendrick Motorsports will not start the Coca-Cola 600 since he stayed in Indianapolis to compete in the Indy 500.
Due to persistent rain and lightning, Larson will not be able to run the whole Indianapolis 500 and Coca-Cola 600 as scheduled. The race is scheduled to begin at 4:45 p.m. ET.
After confirming on Sunday afternoon that Larson would remain in Indianapolis, Hendrick Motorsports gave the go-ahead from the fifth position.
Justin Allgaier, a 24-time winner in the NASCAR Xfinity Series, is ready to take Larson's place in Charlotte.
For his first Indianapolis 500 start, Larson qualified sixth in his No. 17 Arrow McLaren Dallara-Chevrolet.
