The stewards are reviewing an incident between Lando Norris and Yuki Tsunoda after the McLaren team released the Briton into the path of the Japanese driver in qualifying for the Dutch Grand Prix.
During the opening session, the drivers were heading out on track as they bid to get into the top 15, and as Tsunoda was travelling down the pit lane, he came across a hesitant McLaren team.
The mechanics were unsure whether to release their driver from the garage, knowing that, if they did so early, he would have clean air.
Were they to wait, Norris would have been in traffic, so they made a last minute decision to release the 22-year-old.
However, it was too late, and the Japanese driver had to slow down almost to a stop, so he threw his hand up in fury at the Papaya squad.
The Mercedes of George Russell was just behind them, and he too had to slow his car.
“Mega unsafe release there by Norris,” he said on the radio.
Norris, Tsunoda and Russell all made it into the third and final qualifying session, and it looked like it was going to be battle between Red Bull, Ferrari and Mercedes for pole.
Russell performed his first lap on a used set of Softs, and he was set to improve on his second run, before he stumbled across the stricken Red Bull of Sergio Perez, who had spun.
The 24-year-old ended up sixth, ironically behind Perez, while Sir Lewis Hamilton ended fourth, having been competing with Max Verstappen for pole.
It was the Dutchman that took P1 though for the race on Sunday, after narrowly beating the Ferrari of Charles Leclerc.
Carlos Sainz was third in the other Scuderia car, and Norris took seventh ahead of Mick Schumacher, Yuki Tsunoda and Lance Stroll.
