Andy Murray has scratched plans for a training session in Miami because of an ongoing groin injury, according to British press.
Murray had experienced the problem just before Davis Cup, and appeared in just one singles for Britain before deciding to spend the rest of the competition on the sidelines.
Still, it had been anticipated that the injury, which Murray described as a bone bruise, would not delay his off-season training. But now the three-time Grand Slam champion has also cancelled his two-week scheduled session in Miami, which would have begun this week.
The Times said Murray is planning to return to competition at the beginning of next season as scheduled, starting with playing ATP Cup and then the Australian Open.
The 32-year-old can still do fitness work but is not yet hitting, said the Telegraph.
Murray has not played a Grand Slam event since returning from hip surgery, and is aiming just to stay in good physical shape during the best-of-five sets competition.
"I'm not expecting to win the tournament, but if I can play a five-set match and have no ill-effects on the hip," he said, speaking to press a few weeks ago.
Murray is No.126 in the rankings.
