Barry Hearn, president of the World Snooker Tour and Professional Darts Corporation, is “in a good mood” after suffering a heart attack on Sunday.
Hearn, 71, is expected to return home on Wednesday after being operated on.
Her son, boxing promoter Eddie Hearn, posted on social media: “My father was taken to hospital on Sunday after a minor heart attack and had surgery yesterday.
“He is doing well and is going home today in a good mood. Thank you. “
He paid tribute to the NHS for the treatment he had given to his father, who also had a heart attack in 2002.
Hearn gained prominence in the 1970s when he led six-time snooker world champion Steve Davis.
He founded Matchroom Sport and promoted some of Britain’s biggest boxing events from the late 1980s and was also president of the Leyton Orient football club from 1995 to 2014.
