A racing wheel detaches from the McLaren of Lando Norris after he made contact with team-mate Oscar Piastri at the opening of the United States Grand Prix short race.
McLaren F1 team executives Brown and Stella attributed competitors for the crash between Piastri and Lando Norris at the beginning of the United States Grand Prix sprint event.
Piastri, ahead of Norris in the standings by twenty-two points, bounced into his fellow McLaren driver after making contact with the Hulkenberg.
The incident forced out both team drivers from the race, along with the Alonso, who was on the inner side of Hulkenberg.
Brown, the team's chief executive officer, commented to Sky Sports that some of the racing at the start was "unprofessional", stating: "Clearly Hulkenberg hit Oscar and he had no reason being where he was."
McLaren F1 boss Andrea Stella added: "The reaction is that we are displeased that we were denied the opportunity to race."
"It's surprising that some racers with a lot of expertise don't act with appropriate caution. Go to the first corner, ensure you avoid harming competitors and carry on."
McLaren suggested that Stella was mentioning both Hulkenberg and Alonso.
However, 1996 world champion Damon Hill, providing analysis for BBC Radio 5 Sports Extra, said he thought the Australian had not demonstrated enough understanding of the dangers of the opening turn of an Formula 1 event when he decided to cut back to try to pass Norris.
The Australian had a better start than Norris and initially challenged on the outer side on the ascending approach to the corner.
But he then cut back in an attempt to get a advantage on his teammate on the exit, only to make contact with Hulkenberg.
The McLaren driver said: "Not ideal but I did not see what occurred, I tried to move inside on Lando and we were both quite distant from the corner apex and then were struck and it propelled me into Norris. A shame."
His teammate commented: "I just was struck, right? I was not at fault. Behind us things happened and I just got unlucky and was struck because of it. I am unsure. I need to look a bit more carefully. It's more drivers behind just being a bit careless and we are the result of that."
The Aston Martin driver said: "At one point I believed I was in the correct position on the inside, but some vehicles came very quickly from the outer side switching back and then I was there in the middle."
Hulkenberg, who had earned a best qualifying fourth place, said: "Big frustrations. All the good work from yesterday in the bin. Just chaotic."
"Piastri turned in pretty aggressively trying to get the undercut and way out of the first corner but I can't just disappear."
"I had Alonso challenge on the inner side and I couldn't see him any more. I aimed to provide room for him and then Piastri steered inward and the contact was unavoidable."
McLaren will analyze the incident with their racers but only after the race weekend. Both vehicles needed significant repairs before grand prix qualifying at 10 PM BST on the weekend.
Stella said: "In general disappointed but we accept it, we are now concentrating on fixing the cars, there is a lot to do and then we will resume the weekend from there."
"We are in a strong position from our competitiveness point of view so I trust we have the possibility to race, compete fairly and utilize our capabilities."
"Championship points are the most important thing, I prefer not to talk about mal-intent, just prudence. A little more prudence would be beneficial for all involved."
The sprint event was won by Red Bull's Verstappen, who gained ground on both McLaren drivers in the standings - he is now 55 points behind Piastri and thirty-three behind of the Briton.
Stella said: "The consequence is what the maths show - we missed out on eight championship points with both drivers, but we focus on ourselves. We have a very competitive vehicle and two strong drivers. We anticipate just some normal racing."
The Red Bull driver said he was approaching the title race one event at a time.
