LONDON (Reuters) - Rory McIlroy's defence of golf's British Open has been thrown into doubt after he said on Monday that he had ruptured ankle ligaments in a friendly football match with his friends.
"Total rupture of left ATFL (ankle ligament) and associated joint capsule damage in a soccer kickabout," McIlroy wrote on his Instagram account.
"Continuing to asses extent of injury and treatment plan day by day. Rehab already started...working hard to get back as soon as I can," he said, alongside a photograph showing his left ankle in a heavy bandage and brace.
McIlory's showdown with double major winner Jordan Spieth was expected to be the highlight of the Open, which takes place at St Andrews on July 16-19.
