Busch was angry with Logano after his No 18 spun out on the final lap of the NASCAR Monster Energy Cup Kobalt 400 in Las Vegas.
A late-race battle between Kyle Busch and Joey Logano resulted in multiple contact, a spin and a post-race fight on pit road.
Logano was quickly pulled from the center of the fight by members of his crew.
But Busch, who ended up being scored in 22nd, was furious after the race and confronted Logano on pit road as Logano climbed from his vehicle.
"There wasn't too much talking, just a lot of swinging", Logano said.
"It was nothing intentional", Logano said.
Asked to describe the on-track incident that set Busch off, Logano replied: "I don't know".
"We've always said that we've got to take everything and make sure we look at all the video", O'Donnell told SiriusXM NASCAR Radio. Entering turn 3 of the final lap, Kyle Busch and Joey Logano (Keselowski's teammate) drove underneath Keselowski's Miller Lite Ford.
"It was hard to figure out the deal, which lane to pick", Logano said about the decision on where to restart. "It wouldn't turn and I lost brakes". After a hard-charging Keselowski went in front, Danica Patrick blew an engine, bringing out a caution.
Jimmie Johnson was 11th, marking the first time since he became a full-time driver in 2002 that he has failed to have a top-10 finish in the first three races. The Penske Racing star would be credited with his first Top 5 of the season.
The mechanical issue that slowed Brad Keselowski's vehicle led to Busch and Logano quickly catching the No. 2 auto on track. He beat his teammate Keselowski to the line in a photo finish. France echoed O'Donnell's feelings, reiterating that the emotions and high stakes that helped spark Sunday's outburst are inherent in stock-car racing.
The race started with Kyle Busch on Pole, with Brad Keselowski along side.
