• Midfielder treated on pitch during Werder Bremen friendly in Austria • Ajax say 20-year-old is in intensive care after being airlifted to hospital

Ajax’s pre-season friendly against Werder Bremen was abandoned after Abdelhak Nouri required emergency treatment from paramedics on the field.

The midfielder, aged 20, collapsed with around 20 minutes remaining in the game in Zillertal, Austria and there was immediate concern for his condition. An ambulance and helicopter were called on to the pitch while the ground was cleared, though Nouri was eventually airlifted to hospital in what Ajax described as a “stable” condition.

A series of tweets from Ajax’s official account read: “Alarm on and around the field. There is something going on with Abdelhak Nouri. But it’s not clear what. An ambulance is coming on to the field. It looks serious, we hope soon for more info on Abdelhak Nouri. Emergency services are still with Nouri, players look worried. It is serious, we will let you know immediately if there is more clarity. Meanwhile a trauma helicopter landed on the field. People are asked to leave the stadium.”

The final update late on Saturday evening said Nouri was in intensive care but “out of danger”.

Nouri reportedly received CPR on the field before leaving in the helicopter. Around 15 minutes after the news first broke, Ajax tweeted: “Update | Nouri had heart arrhythmias. He is stable, has a heartbeat and is asleep. He is going in the helicopter to hospital. Thanks so much for all your support.”

Nouri made 15 appearances for Ajax’s first team last season, including three in the Europa League, and scored on his senior debut in a 5-0 win over Willem II in the KNVB-Beker.
