Isner dealt Australian Open KO
Another seed has been forced out of the Australian Open, with big-serving American John Isner pulling out on account of injury.
Isner, seeded 13, had been struggling with a knee injury in recent weeks and his doctors have advised him to sit out the opening major of the season which gets underway on Monday.
"I am extremely disappointed to announce that I have to withdraw from the Australian Open. I have been feeling some discomfort in my knee and have recently learned that I have a bone bruise," Isner said on Thursday.
"My doctors have told me that continuing to play on the knee could result in a more serious injury, so I have regrettably decided not to compete in Melbourne and use the time to fully recover."
Isner's place in the draw will go to a lucky loser from qualifying
