Colin Montgomerie's fears over Rory McIlroy injury

If Rory McIlroy does return to the fray this week in defence of his PGA Championship crown, Colin Montgomerie hopes the Irishman is in the right shape to do so.

Five weeks after damaging ankle ligaments in a soccer kickabout that forced his withdrawal from The Open at St Andrews last month, McIlroy has arrived in Whistling Straits, the links-style monster by the shores of Lake Michigan in Wisconsin.

He appears ready to play in Thursday’s opening round but former Ryder Cup-winning captain Montgomerie, who will also play this week as reigning Senior PGA champion, is concerned if the comeback is a premature one.
