Both of NASCAR’s most consequential regular season points battles took a big swing with five laps left in Stage 2 of Monday’s FireKeepers Casino 400 at Michigan International Speedway.

Kyle Larson, who entered the race with the regular season points lead, was racing inside of the top 10 on one of the race’s many chaotic restarts when he got loose in the middle lane and spun.

Larson’s No. 5 Hendrick Chevrolet backed into the outside wall in the direct path of Bubba Wallace, who clattered into the Californian and sustained significant front-end damage to his No. 23 23XI Toyota. At the same time, a stack-up behind Larson led to more crashes that included Chris Buescher, Joey Logano, Christopher Bell, Chase Briscoe and Todd Gilliland.
