Isner Withdraws from Australian Open Due to Knee Injury
Top-ranked American John Isner has withdrawn from the Australian Open due to a knee bone bruise that also caused him to pull out of Hopman Cup earlier in the year.
“I am extremely disappointed to announce that I have to withdraw from the Australian Open,” Isner said in a statement. “I have been feeling some discomfort in my knee and have recently learned that I have a bone bruise. Doctors have told me that continuing to play on the knee could result in a more serious injury.”
