McLaren Formula 1 driver Carlos Sainz Jr will be demoted three places on the Canadian Grand Prix grid for impeding Alex Albon during Montreal qualifying.
The penalty drops Sainz from ninth on the grid to 12th, though he could regain a position if 10th-placed qualifier Kevin Magnussen has to start from the pitlane following his Q2 crash.
"It is an incident I apologise for and the whole team apologises," said Sainz.
"It ended up costing us three places."
It was prompted by an incident in Q1 in which Sainz blocked Albon's Toro Rosso through Turns 1 and 2, just after Albon had let the McLaren through while it was on a fast lap and he was preparing for a run.
The stewards' announcement of Sainz's penalty explained that he "was on the radio with the team, talking about tyres" and that McLaren's warning of Albon approaching on a flying lap "was given too late".
The incident did not prevent Albon from getting into Q2 with a later run, and he played down Sainz's actions afterwards.
"I didn't really do a first big push, and then the next lap I had traffic so I basically had one lap to get into Q2 and I didn't think it was good enough," said Albon, who qualified 14th.
"But when I saw [the time] I was like, I'll take that!"
