(AP) MELBOURNE, Australia — Rafael Nadal will miss up to four weeks of competition with a knee injury that forced him to quit in the third set of his Australian Open quarterfinal against Andy Murray.
The second-ranked Nadal had his right knee assessed in Spain and was advised to get rest and treatment for four weeks before returning to tournament play.
Nadal said it was not the recurrence of the tendinitis that sidelined the six-time Grand Slam singles champion for periods of 2009.
He was unable to defend his Wimbledon title last year because of the tendinitis and has not reached another Grand Slam final since his five-set win over Roger Federer at last year's Australian Open.
MRI and ultrasound tests showed a small tear at the back part of Nadal's right knee, which can be treated with physiotherapy and anti-inflammatory treatment, Dr. Angel Ruiz-Cotorro said in the statement.
Nadal expects to miss the ATP tournament starting Feb. 8 at Rotterdam, where he lost the final to Murray last year.
"After two weeks and depending on the results of the different tests and controls, he will steadily resume his sporting activity with a total recovery time to resume competition in fours weeks," Ruiz-Cotorro was quoted as saying.
Nadal said he was happy the latest injury setback was not lingering tendinitis.
"I feel good and I am only thinking now of recovering well," the 23-year-old Spaniard said. "My main goal right now is to get ready again and fit to play the upcoming events once I am able to compete."
