Ronnie O'Sullivan allowed to wear trainers at English Open because of ankle injury

World Snooker has allowed Ronnie O'Sullivan to wear trainers during his second round match at the English Open.

The 41-year-old wore blue trainers during his 4-1 victory over Zhang Anda in the opening round yesterday due to a sprained ankle but was told by the game's governing body to correct his footwear for his match against Mark Davis.
