Month-long absence on cards for Isner
John Isner suffered a stress fracture in his foot in Sunday's Miami Open final and is facing around a month on the sidelines.
The big-serving American was struck down by the problem late on in the first set of his 6-1 6-4 defeat at the hands of Roger Federer.
Isner did manage to battle on until the end of the match but struggled badly as his opponent took full advantage to claim the 101st ATP title of his illustrious career.
The 33-year-old said afterwards that he was hopeful the injury was nothing serious but it now appears he suffered a stress fracture.
It will take between four and six weeks to recover from, which will rule him out of tournaments such as the Monte Carlo Masters, Barcelona Open and possibly the Madrid Open in early May as the clay-court season gets into full swing ahead of the French Open from May 26.
