Ajax midfielder Abdelhak Nouri is stable and had a pulse after collapsing during a pre-season friendly.
The 20-year-old fell to the ground approximately 70 minutes into the game against Werder Bremen.
Medical services rushed to Nouri’s aid where CPR was reportedly administered, before he was airlifted to hospital in Innsbruck.
Nouri’s Ajax team-mates looked on in shock, some crouching down with their shirts over their faces, as they waited for news on the situation.
The game, which was taking place in the Lindenstadion in Hippach, Austria, was later abandoned.
It was called off approximately 15 minutes after Nouri began receiving treatment.
Ajax issued an update to their supporters over social media as Nouri made his way to hospital, where they confirmed that he had suffered from cardiac arrhythmias.
“There was talk of heart rhythm disorders. He is stable, has heart rate and is asleep,” they tweeted.
“Nouri is now flown by helicopter to the hospital. Thanks so much for all your support.”
Supporters were soon asked to leave the stadium as a helicopter landed on the pitch to transport Nouri to hospital.
Ajax were losing 2-1 at the point of the game being abandoned.
Nouri is one of Ajax’s biggest prospects after winning the Player of the Year award for Jong Ajax, who play in the Jupiler League, last season.
He travelled with the Ajax squad to the Europa League final against Manchester United, but played no part in the game.
