World number one Rafael Nadal damaged a muscle in his right leg during his Australian Open quarter-final defeat by Spanish compatriot David Ferrer and needs around 10 days to recover.
Nadal, who is recuperating at home on the Balearic Island of Mallorca, received scan results on Tuesday that confirmed the extent of the injury, he said in a statement on his personal website.
"Doctors estimate a recovery period of about 10 days from today, Feb. 1," the statement said.
The French Open, Wimbledon and US Open champion, who failed in Australia in his bid to hold all four Grand Slams at the same time, should be fit for Spain's Davis Cup match against Belgium on March 4-6 and the Masters events in Indian Wells and Miami later that month.
