Four-times world snooker champion Mark Selby is considering his future because the sport has adversely impacted his mental health, he said after his 10-6 first-round defeat by Joe O’Connor on Monday.

Selby, who won the world title in 2014, 2016, 2017 and 2021 and was runner-up last year, was disappointed with his performance against Crucible debutant O'Connor as he suffered his first opening round loss in the tournament since 2018.
