NORTH WILKESBORO, N.C. (AP) — Ricky Stenhouse Jr. threw a right hook at Kyle Busch, and suddenly, an otherwise boring All-Star Race at North Wilkesboro Speedway had NASCAR fans buzzing heading into next weekend’s marquee Coca-Cola 600 at Charlotte.

Busch had wrecked Stenhouse on the second lap of the $1 million race Sunday night in a move that looked like retaliation for how Stenhouse had raced him earlier. Stenhouse drove his damaged Chevrolet to Busch’s pit stall and parked it, and with no way to get out of the track while the race was going on, stewed in street clothes for hours until Busch arrived at his hauler.

That’s when Stenhouse, after a brief conversation, threw a right hook at the driver of the No. 8 Chevrolet, setting off a brief melee that involved members of each driver’s crew — and Stenhouse’s father. The brawl was eventually broken up, but not before more words were exchanged from both sides and Stenhouse vowed, “I’m going to wreck you at Charlotte.”
