Red Bull's Max Verstappen and Mercedes' Kimi Antonelli were knocked out of the Austrian Grand Prix after colliding on the first lap of the race.

The retirement is the first of the season for Verstappen and just the third time in four years that the four-time world champion has failed to finish a race.

The stewards investigated the incident after the race. Antonelli was assessed a three-place grid penalty which he will serve at the British GP next weekend at Silverstone.

It's been a rough weekend for Verstappen, who qualified seventh and entered Sunday 43 points behind McLaren's Oscar Piastri for top position in the drivers' standings.
