Sergio Reguilon has revealed that he asked referee Andre Marriner to halt Newcastle's Premier League meeting with Tottenham after spotting a collapsed spectator in the St James' Park crowd.
The match was suspended just before half time with the players eventually returning to their changing rooms at the request of the match officials.
After a brief pause while the spectator received treatment, both teams reemerged to play the remainder of the first half.
Reguilon was the player who drew the referee's attention to the situation and he detailed what happened in his post-match interview.
"I saw one guy lying down and one man doing this [miming CPR]. I was very nervous. I went to the referee to say: 'look at this, we cannot play, stop the match'. The referee and linesman looked there and stopped the match," he told Sky Sports after the game.
