A wheel flies off the McLaren of Lando Norris after he collided with team-mate Oscar Piastri at the start of the United States Grand Prix sprint race

McLaren Formula 1 bosses Zak Brown and Andrea Stella blamed rival drivers for the crash between Oscar Piastri and Lando Norris at the start of the United States Grand Prix sprint race.

Piastri, leading Norris in the championship by 22 points, bounced into his team-mate after colliding with Sauber's Nico Hulkenberg.

The crash took both McLaren drivers out of the race, along with Aston Martin's Fernando Alonso, who was on the inside of Hulkenberg.

Brown, McLaren Racing's chief executive officer, told Sky Sports some of the driving at the front was "amateur hour", adding: "Clearly Nico drove into Oscar and he had no business being where he was."
