Barry Hearn, the sports promoter who is chairman of Matchroom, the World Snooker Tour and the Professional Darts Corporation, has tested positive for coronavirus.

Matchroom and the PDC both tweeted that the 72-year-old, who had surgery after suffering a minor heart attack earlier this year, is asymptomatic and is now self-isolating.

The statement said: “Matchroom chairman Barry Hearn has tested positive for Covid-19 and begun a period of self-isolation in accordance with UK government guidelines.

“Barry feels well and is not displaying any symptoms.

“Additional staff and family members have also been tested and all found negative.”

On Thursday, Hearn’s son Eddie announced he had tested positive for coronavirus and he therefore left the Matchroom Boxing bio-secure bubble ahead of Joshua Buatsi’s bout with Marko Kalic on Sunday.
