For his part, Kyle Busch had already indicated that he would leave the matter in NASCAR's hands and not pursue other avenues of redress - which could have included reporting the matter to the police for possible criminal assault.
"NASCAR is taking the situation seriously and is looking into it, and making their decisions based what facts they can discover ... "Whatever they feel best to protect their sport and to protect what we have going on here is to their best discretion," said Busch. "I'm all for whatever they decide to do."
He concluded: "I'm going to leave it up to NASCAR and let them decide what they feel is best."
Busch himself remains on probation until June 15 for an unrelated disciplinary matter dating from an on-track clash with Richard Childress Racing driver Kevin Harvick at Darlington in May. That clash saw an estimated $30,000-worth of damage done to Harvick's car after Busch shunted it to one side, after Harvick used it to block the entrance into pit lane. Both drivers were found at fault, Harvick also receiving probation and both drivers additionally fined $25,000.
Asked about whether Saturday's incident represented the latest step in an ongoing feud that had been brewing between the Childress and Busch camps, Kyle replied: "That's not something I can answer. I wasn't the aggressor or the instigator here. All I can say is I was just trying to head back to my hauler and deal with my own business."
The altercation started after Kyle Busch, driving the #18 truck for his own Truck Series team, had been unhappy with the way that RCR rookie Joey Coulter overtook him for fifth place on the final lap and gave him a bump on the cool-down lap after the chequered flag.
Childress showed up at the Busch garage 30 minutes after the end of the race having reportedly taken offence at Busch's comments, then handed his watch to his grandson Austin Dillon (another competitor in the Truck series) - and allegedly got the 26-year-old Busch in a headlock before proceeding to hit him multiple times in the face. Busch fell to the ground and curled up "in a defensive position" but when he tried to get up, the 65-year-old Childress had again reportedly tried to hit him.
