The handful of fans allowed into the Crucible on Friday morning were treated to some drama as defending champion Judd Trump quickly fell behind to Tom Ford in the opening match of the World Snooker Championship. 

With the match under way, British Prime Minister Boris Johnson announced that the experiment of allowing spectators into sporting events this week would need to quickly end due to fears over rising numbers of coronavirus cases, but those who did make it to Sheffield got plenty of entertainment. 

World Snooker later released a statement saying: "From tomorrow the event will be played behind closed doors.

"WST remains hopeful that a small crowd will be allowed for the final on 15 and 16 August, and will follow Government advice on this."

Trump, the favourite here after piling up a record-breaking six titles in the abridged season to date, lost the opening three frames before battling back to end the session 5-4 down. 

Ford was on track for a 147 in the very first frame before missing the 13th red. 

He then took the next two as he punished mistakes from Trump, who was unable to capitalise on the few opportunities presented to him. 

The best chance came in the third frame when Trump rallied from 64-22 down and needed only the final black to take the frame, but he left himself with a difficult final shot, missed, and watched Ford take it instead. 

A break of 104 got Trump on the board before the mid-session interval and he cut the deficit to one with a break of 62 in the fifth. 

Ford responded with a clearance of 140 to restore his two-frame advantage and moved 5-2 up after opening the seventh with a break of 61. 

But Ford gave Trump a let-off in the next frame, missing what looked a routine blue, and a break of 53 saw Trump cut the deficit to two. 

The match took another key turn in the ninth frame. With Ford 48-0 up, he missed a straight pink and Trump, under pressure, capitalised with a break of 61 to make it 5-4. 

In the morning's other game, Stuart Bingham leads Ashley Carty 5-4.  

On the disappointment for the spectators, WST chairman Barry Hearn said: "It's a great shame for people who had those golden tickets, but in the circumstances we are now living in we have to accept the decision and move on."
