The World Snooker Championship final between Mark Williams and Zhao Xintong was briefly halted on Sunday due to a medical emergency involving a spectator.
The interruption came during the sixth frame of the match at the Crucible Theatre.
Referee Desislava Bozhilova stopped play as Williams was preparing to take a shot, using the rest to line up a long red.
Both players were instructed to return to their seats while medical attention was provided to an unwell fan in the audience.

The delay was short-lived, with the affected spectator soon leaving the venue for some fresh air.
Dennis Taylor, commentating for the BBC, explained the situation to viewers: "There is someone not feeling quite so well, but I don't think it is anything serious I can see in the crowd. [They] might just need a couple of minutes."
The Crucible fell quiet as officials attended to the spectator.
Taylor reassured the audience: "It will only be a couple [more] seconds... and I think we should be OK. Just someone not feeling so well, out for a bit of fresh air."
The delay lasted only moments before the match could continue.
The spectator was seen walking up the stairs and exiting the venue.
The interruption appeared to affect Williams' concentration when play resumed.
Having had his focus broken by the delay, Williams missed a red to the bottom-right corner that he would normally have been expected to pot.
The opportunity had arisen after Zhao made an error when attempting to roll up to the pack of reds.
Zhao had come up too short, leaving a stray ball available for Williams.

However, the Welsh player couldn't capitalise on the chance following the unexpected break in play.
Zhao, who had performed strongly throughout the opening session, also missed his own opportunity moments later.
This uncharacteristic error came despite the Chinese potter having done very little wrong up to that point.
Zhao went on to finish the first session 7-1 up to put himself in a commanding position ahead of the evening session.
