'You might not see me until next year': Rory McIlroy may miss rest of season

Rory McIlroy might not play again in 2017 as he continues to struggle with the injury which has limited him to 13 events in a winless season, his third in succession without a major title.
McIlroy came into the US PGA Championship as the pre-tournament favourite on the back of top-five finishes in his last two starts and a brilliant record at the host venue of Quail Hollow, including two wins and a course record of 61.
