Tuesday’s League One match between Leyton Orient and Lincoln City was abandoned after 82 minutes following a medical emergency in the crowd.
Stewards initially raced over to an area at the front of the East Stand at Brisbane Road with some home fans calling for play to be stopped.
The match kept going for a few minutes while the supporter was being treated, before one fan ran on to try to alert referee Stephen Martin.
The game continued until around 20 Orient supporters sat on the pitch at the home end as CPR continued on the fan and play was finally halted.
Orient were leading 1-0 at the time through Joe Pigott’s 10th-minute goal.
The decision to abandon the game was announced at 22:25 BST, almost an hour after the match was paused, with medics still attending to the supporter.
“Tuesday’s fixture against Lincoln City was abandoned due to a medical emergency in the East Stand of Brisbane Road,” an Orient statement said.
“The thoughts of everyone at Leyton Orient Football Club are with the individual involved and their loved ones at this distressing time.
“The club would like to thank all supporters in attendance at Brisbane Road this evening for the understanding and compassion shown, during a very difficult situation.
“The club will provide a further update in due course.”
