Salzburg defeated Mexican Pachuca after a prolonged event in Cincinnati.
In the 54th minute, the match was interrupted due to a storm with heavy rain, thunder, and lightning.
Only after a 97-minute break could the match be resumed, writes The Athletic.
It was an exceptional situation and you had to do something else. Some stretched, others sat on the exercise bike, some got a massage and some ate a banana or a power bar. I hope it doesn't happen again, says winner Karim Onisiwo to the club's website.
He decided the match in the 86th additional minute – with twelve minutes left to play.
John Mellberg started on the bench and was substituted in the last two minutes.
