McLaren team principal Andreas Seidl says Carlos Sainz Jr escaped with just some bruising to his hands following the safety car restart crash that stopped the Tuscan Grand Prix.
Sainz was caught up in the middle of the melee when the safety car pulled off and the back of the pack started accelerating before the race leaders had resumed racing.
Running behind Antonio Giovinazzi's Alfa Romeo, Sainz could not avoid hitting the back of the Alfa Romeo when it ran into Kevin Magnussen's Haas.
The resulting crash eliminated Sainz, Giovinazzi, Magnussen and Nicholas Latifi's Williams and brought out the first of two red flags in the race.
Asked afterwards how Sainz was, Seidl said: "I think the most important thing is that Carlos and, as far as I know all the other guys also, are okay. That's the most important thing.
"I think Carlos had a bit bruised hands but nothing big, which is good."
Sainz said he suffered no major injuries following the heavy impact.
"I am fine. Only a blow to the wrist and hand, but honestly it does not hurt me at all. I am perfectly fine," he said.
He claimed that the nature of the restart had triggered a "very dangerous" situation for those in the middle of the pack.
"I'm happy that everyone is well, because apart from the frustration of not finishing the race in this way, I think what happened today is a very dangerous situation," the Spaniard told Movistar.
"When suddenly you go to 250 kph and you find cars stopped in the middle of the track is a very, very dangerous situation that should not be repeated.
"What is clear is that in the rear half of the grid we thought the race had been restarted, or someone has believed it, and then we had to brake all and there was a domino effect that we have been bumping all with everyone.
"I was coming from the last and hit the car in front, taking the slipstream to attack and when they have begun to accelerate and I found the chaos in front [it] has been a feeling that I do not wish to anyone, because it has been at a very high speed and of course, a very dangerous situation."
