While Denny Hamlin celebrated his 61st Cup Series win on Sunday afternoon at Las Vegas Motor Speedway, two former teammates clashed on pit road.

Fox Sports cameras showed Trackhouse Racing driver Ross Chastain and Spire Motorsports driver Daniel Suarez in a heated confrontation next to their cars. They put hands on each other before a PR representative separated them.
An official and a Trackhouse Racing crew member also stepped in as the two drivers continued with their argument at Las Vegas Motor Speedway. They ultimately separated without the altercation turning violent.
Not that the two drivers shy away from physical altercations. Chastain once punched Noah Gragson on pit road at Kansas Speedway while Suarez tackled and fought Michael McDowell at Phoenix Raceway.

So what exactly happened? Not many people really know beyond Chastain, Suarez, and their teams. Nothing that appeared egregious happened during the closing laps of the Pennzoil 400 at Las Vegas Motor Speedway.
The two drivers did have one close run-in with about four laps to go. Chastain went to pass his former Trackhouse Racing teammate on the outside, but Suarez slid up the track.
Chastain came close to the wall in the No. 1 Chevrolet, but he did not make contact. Chastain then drove up next to Suarez on the cooldown lap and side-swiped Suarez's No. 7.
The Trackhouse Racing driver did not provide any comment about the confrontation to media members after the race. Suarez, however, spoke to Frontstretch and other outlets in the garage area.

"Our relationship has always been a little weird," Suarez said. "Almost like a little bit of two-faced on his part for some reason, and today, I saw actually what I thought he had in his mind for a while.
"But I don't have any hard feelings toward anyone. I'm doing my thing, having a great time, and you just saw that he thinks that way."
Chastain and Suarez spent four seasons as teammates at Trackhouse Racing. They began working together in 2022 after the team bought Chip Ganassi Racing's charters and assets.
They never had any public conflict while referring to each other as amigo, but Suarez's comments on Sunday make it appear that they had some underlying issues.
