Colin Montgomerie's fears over Rory McIlroy injury

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.
