Ronnie O'Sullivan is set to begin his Coral UK Championship campaign on Thursday, despite suffering a nasty ankle injury.

O'Sullivan is targeting a fifth victory in the tournament, which he first won as a 17-year-old in 1993, but a mishap while running in Essex this week means he will not go into the York event in the best physical shape.

The 38-year-old posted a picture on Twitter of him resting up his left ankle, which was severely swollen, adding the note: "Might be one legged Snooker at the #UKChampionship on Thursday."

However, tournament organiser World Snooker has confirmed O'Sullivan "intends to play" his first-round match against Daniel Wells.
