Ferrari's Charles Leclerc won the Monaco Grand Prix on Sunday to become the first home winner of Formula One's showcase race since Louis Chiron raced around the city streets in 1931.
It was the first time the 26-year-old had stood on the Monaco podium in six attempts and came after two standing starts from pole position in a race halted when first lap collisions took out a fifth of the field.
McLaren's Oscar Piastri finished second, 7.1 seconds behind, with Ferrari's Carlos Sainz third.
Red Bull's championship leader and 2023 Monaco winner Max Verstappen started and finished sixth, only the third time in eight races this season that the triple world champion has been beaten.
Red Bull said Perez, who started the day third in the championship led by team mate Max Verstappen, did not have to go to the medical centre.
"It was a typical lap-one racing accident. Two drivers who both didn't want to bail out and didn't give enough room on a tight track like Monaco, and I was the unlucky victim there," said Hulkenberg.
Stewards reviewed the incident and decided to take no further action, a relief for Magnussen who is in danger of a race ban.
The two Alpines of Pierre Gasly and Esteban Ocon also banged wheels at Portier as they fought for position, with Ocon's car lifted into the air.
"What did he do? Why did he try to attack me?" exclaimed Gasly. "The whole car is damaged now."
Ocon, who did not re-start, was given a 10-second penalty for causing a collision which will likely translate into a grid drop at the next race.
Ferrari's Charles Leclerc led from pole position with McLaren's Oscar Piastri second.
All cars returned to the pit lane before a second standing start, which went off cleanly, in their original order.
That was good news for Ferrari, who had seen Carlos Sainz go off at Casino before the collision and after an incident with Piastri.
The Spaniard, who started third, was able to get going and return to the pits.
Leclerc was bidding to become the first Monegasque to win his home grand prix since 1931.
