FANS have been seriously injured after a huge banner collapsed - with helicopters called in to help tackle the emergency.
A canvas crashed down from a crane to cause chaos behind a goal as Stevo and Twente prepared for a pre-season friendly in the Netherlands.
The fire brigade said several supporters but "less than 20" were hurt.
The worrying scene was treated as a major incident and the match postponed.
Players rushed over to help and some fans held up a large metal frame to possibly prevent more injuries.
