Ty Dillon, Ty Gibbs advance to final round of NASCAR In-Season Challenge

Ty Dillon and Ty Gibbs will race head-to-head for $1M on Sunday at Indianapolis Motor Speedway. 

Dillon and Gibbs advanced to the final round of NASCAR's inaugural In-Season Challenge on Sunday at Dover Motor Speedway after beating John Hunter Nemechek and Tyler Reddick, respectively, in their matchups. 

Dillon, the No. 32 seed, will face Gibbs, the No. 6 seed in the Brickyard 400, with the highest finishing of the two winning $1M. 

Gibbs advanced with a fifth-place finish to Reddick's 12th-place effort, while Dillon finished 20th, besting Nemechek (21st) by one position to move on. 

Dillon advanced by beating Denny Hamlin at Atlanta, Brad Keselowski at Chicago, Alex Bowman at Sonoma and Nemechek at Dover on Sunday. 

Meanwhile, Gibbs advanced by beating Justin Haley at Atlanta, AJ Allmendinger at Chicago, Zane Smith at Sonoma and Reddick at Dover on Sunday. 

Gibbs is 16th in the Cup Series standings following Sunday's race at Dover while Dillon is 30th — but the only number that matters in determining which driver takes home the prize at Indy is their finishing position. 

The Brickyard 400 will go green shortly after 2 p.m. ET on Sunday, with coverage on TNT and SiriusXM NASCAR Radio.
