Justin Allgaier is on standby to drive Kyle Larson’s No. With Larson attempting the Memorial Day weekend double starting with the Indianapolis 500 followed by the Coca-Cola 600, any hold ups or mishaps could require help from a relief driver in Charlotte. Allgaier, who competes for JR Motorsports in the Xfinity Series, will drive Larson’s car if needed. Larson successfully made the trip from Indianapolis to North Wilkesboro Speedway last weekend for the NASCAR All-Star Race with time to spare. Weather Underground calls for thunderstorms in Indianapolis for much of Sunday, while Concord could also get a scattered thunderstorm on race day.
