Top-ranked American men's tennis player John Isner was forced to retire from the 2014 Australian Open after suffering a foot injury, according to ESPN Tennis on Twitter:

The injury led Isner to retire from his first-round match against Martin Klizan, who was on his way to victory already having taken a two-sets-to-love lead.
The 28-year-old did play two points in the third set before calling it quits. The retirement marks the third time since 2008 that Isner has bowed out in the opening round of the Australian Open.
Tennis reporter Matt Cronin adds some details to the injury:
Isner's ankle was killing him, couldnt have played beyond 2nd win or lose TB, 1st hurt it in Perth, plans are to play @DavisCup v Britain— Matt Cronin (@TennisReporters) January 14, 2014
Isner's foot injury is definitely something to monitor for moving forward. After all, he suffered an ankle injury at the Hopman Cup at the start of the year and has to carry around a massive 6'10" frame. And two injuries within the first month of the season doesn't bode well for any player, given the demands of today's grueling ATP tour.
