Mick Schumacher's chances of scoring his first points in Formula One evaporated in the Miami heat on Sunday after he collided with his mentor Sebastian Vettel with just four full laps of the Grand Prix remaining.
The 23-year-old German, who went through his debut season for Haas last year without picking up a point, was challenging Esteban Ocan for ninth spot on lap 53.
But the incident with Vettel left Schumacher needing to stop for a new wing and he ended up frustrated in 15th place.
The stewards ruled that neither driver was to blame for the collision and unsurprisingly, given their close relationship, there was no finger pointing from the drivers.
"Obviously a shame that we made contact and both of us out of the race, out of the points," said Vettel, who was put out of the race by the crash.
"I'm disappointed for Mick and myself obviously that the two of us lost a good opportunity to score points today.
"I don't know, I did not expect him, I need to have a look again. When I saw him, it was obviously too late, so we made contact," said the Aston Martin driver.
Do you think Seb and Mick's relationship will be affected after the Miami crash? Please share your thoughts in the comments section below.
Schumacher's father, seven-times world champion Michael, was Vettel's boyhood hero and took him under his wing early in his career.
Schumacher senior has not appeared in public since he suffered severe head injuries in a skiing accident in the French Alps in December 2013.
Vettel has taken on the role of offering advice and a helping hand to Mick Schumacher, who was not surprised there was no hostility in Vettel's reaction to the incident.
"No, the same from my side," he said, "It's nice that I can learn from him, he's so valuable to me as a friend, so yeah, we'll see. Obviously we're all racers.
"Obviously, it's hard to say and hard to judge from inside the car.
"So, I have to wait and see how it looks from the outside. But I'm sure it will also be good for me to see what Seb thinks about it. We'll just have to move on from here.”
Schumacher still managed to take some encouragement from his performance where had looked well placed for a top 10 finish.
"I think the pace was there," he said. "It all was looking good but unfortunately the last few laps were a bit chaotic."
