Willie Collum faced with power outage chaos as Austria vs Denmark plunged into darkness

Scottish ref Willie Collum was forced to delay Austria vs Denmark by more than 90 minutes after a power outage caused chaos in Vienna.

While Steve Clarke 's team get ready for their clash with Armenia, SFA whistler Collum is on international duty too and he was named the man in the middle for the Nations League encounter.

It was two teams familiar to Scotland as we faced both Austria and Denmark in World Cup qualifying.

They met again in the second game of League A Group 1 but it could have got off to a smoother start.

More than 50,000 fans were seated in the Ernst-Happel Stadion as kick-off approached and there was widespread confusion when all the lights in the stadium suddenly went out.

But those expecting an appearance from The Undertaker were left disappointed as all they got was a decision from Collum to delay kick-off until the issue was resolved.

The stadium announcer confirmed there had been a power outage and the game was delayed from its initial time of 8.45pm CET (7.45pm UK time) until 10.15pm.

Fans in the stadium used their phones to light the stadium up and there was a huge cheer when the lights eventually came back on.

The game then kicked off more than 90 minutes late with Tottenham midfielder Pierre-Emile Hojbjerg giving Denmark the lead at half-time.
