Kyle Larson's Indy 500 Debut Faces Rain, NASCAR Adjustments
Arrow McLaren has decided not to use Tony Kanaan as a stand-in for Kyle Larson in the Indianapolis 500, should weather delays force Larson to leave for the NASCAR Cup race. The team will focus on race preparations and Kanaan's role as sporting director. IndyCar's new rules prevent mid-race driver substitutions, complicating potential stand-in scenarios. If Larson must leave, rookie Nolan Siegel is the only eligible substitute, but the team may opt for Larson to start and then withdraw to meet NASCAR's playoff requirements.
