-- NASCAR returned to the historic Indianapolis Motor Speedway on Friday as drivers prepared for a full weekend of racing at the Brickyard. The NASCAR O’Reilly Auto Parts Series field completed a 50-minute practice session ahead of Saturday’s 100-lap race. Only one driver in the field has previously won at Indianapolis: defending series champion Justin Allgaier. NASCAR Cup Series driver Ross Chastain, who is also competing in the O’Reilly Series race, topped the practice leaderboard. The NASCAR O’Reilly Auto Parts Series race at Indianapolis Motor Speedway is scheduled for 4 p.m. Saturday and will air on CW25.
