The NASCAR Camping World Truck Series at Gateway Motorsports Park was delayed because of weather, but there was plenty of action once Saturday night's race finally got started.
After a wreck on the 41st lap, drivers John Wes Townley and Spencer Gallagher went after each other in an on-track wrestling match.
It's unclear what set them off, but they got out of their respective vehicles and were immediately jawing at each other. Townley initially threw Gallagher to the pavement. Gallagher got back up and tackled Townley, getting "points for the takedown" from the FS1 announcers.
The wreck that initiated the fight occurred after Tyler Reddick bumped Matt Crafton into the wall and spun out into the middle of traffic.
