Yuki Tsunoda has apologised to teammate Pierre Gasly after colliding with the Frenchman during the British Grand Prix.
Tsunoda attempted to pass Gasly at Village in the early stages of the race, but spun into his teammate, sending them both off the road and ultimately condemning Gasly to retirement.
Tsunoda was issued a time penalty and finished the race last of the 14 classified runners.
To add insult to injury for the Red Bull-owned team, it emerged that the debris that had lodged itself into Max Verstappen's floor and caused the Dutchman to lose performance had come from an AlphaTauri, likely caused by the contact between Tsunoda and Gasly.
Writing on Instagram after the race, Tsunoda accepted responsibility for the incident and apologised to Gasly and his team.
Tsunoda apologises for incident
"About the collision with Pierre, huge apologies to my team, people in the factory, fans and especially Pierre Gasly," wrote Tsunoda.
"That was completely my mistake. I'll be back stronger in Austria."
Tsunoda's Silverstone mishap comes just one race after the Japanese driver embarrassingly retired from the Canadian Grand Prix after sliding off-track as he exited the pit lane.
