Kevin Harvick came back to work on Sunday at Martinsvulle Speedway realising that he had some serious bridge repair work that needed doing in the wake of the Saturday night Camping World Truck Series race at the half mile short track the previous day.

Harvick was furious after being spun out of the race in the closing stages by Ty Dillon, grandson of Richard Childress who owns the team that Harvick races for in the Cup Series - although he's due to leave the squad after the end of the current season.

As the two trucks made their way back to pit road for repairs, Dillon - clearly aggrieved at the way Harvick had been racing him prior to the incident - repeatedly tried to spin Harvick. In retaliation, Harvick then parked across Dillon's pit stall to ensure the #3 couldn't get in for repairs. Dillon's pit crew, incensed, crowded around Harvick's vehicle and someone even allegedly threw a rubber mallet at Harvick's truck before NASCAR officials intervened and the #14 was ushered off down pit lane.

"I don't care what they throw at me," an angry Harvick snapped as he stormed out of the track. "That's exactly the reason I'm leaving RCR is because you've got those punk-ass kids coming up." As well as Ty, his brother Austin will takeover the #29 Cup car when Harvick leaves for Stewart-Haas Racing next month.

"I cut him slack all day and, you know, he just dive-bombs me in there, dumps me ... It's a shame you've got to get taken out by some rich kid like that," he added. "Exactly the reason why I'm leaving RCR because you've got those kids coming up and they've got no respect for what they do in this sport and they've had everything fed to them with a spoon."

"I don't care what Kevin Harvick says," Dillon responded. "I don't think anybody does.

"I used to look up to that guy but I guess he doesn't understand the circumstances of what's going on," he continued. "To tear up a truck after the race and act like a punk on the track and on pit road and stop on pit road in my pit stall when my guys were coming out, that was pretty ridiculous."

"I'm very disappointed, that's all I can say," was Childress' own response after a visit to the NASCAR hauler to discuss the matter. "I've got too much class to say what I want to say right now ... When I say it, I will say it to his face."

As a driver for Richard Childress Racing, Harvick is currently tied in third place in the Chase standings and has a lot to loose if he falls out with the team and its owner, so on Sunday Harvick was showing contrition to try and cool things down before the Goody's Headache Relief Shot 500 NASCAR Sprint Cup Series race.

"You go back and look at the things that happened, and sometimes you regret the things that you say for sure. Yesterday was definitely one of them," he told Fox Sports 1. "I think yesterday was just some frustration on how the race ended.

"You try to do the right things, and yesterday I didn't do the right thing," he admitted. "Obviously, when those emotional situations come about; you say things that you really don't want to say. I just want to apologize to all of those guys, work hard today and try and do everything we can to win the [Cup] race [on Sunday.]

Harvick has been with Richard Childress Racing since his Cup d?but in 2000, and despite his susprise decision to strike out for pastures new with SHR in 2014 it was thought that the split was amicable and hadn't affected his ability to make a run for this year's title.

Harvick said that he hadn't spoken directly with Ty Dillon yet and would wait for things to come down before reaching out.

"I think it's best for all of us to just cool down and have a sensible conversation about things that are going," he said. "I wish that's what I would have done yesterday. It's one of those situations that you don't want to be a part of, but I don't have anybody else to blame but myself."
