It appears Appendix surgery was not the only thing that world No. 3 Rafael Nadal had on his injury check-up list this coming off-season.
The Spaniard, who withdrew from the Paris Bercy and ATP World Tour Finals to deal with his appendicitis and injured back, but it appears he will now have to add his knees to the list of troubles.
While Nadal is not feeling any pain from his knees at the moment, he is using the time off as an opportunity to get an examination done on them. His knee inssues have cost him portions of various seasons over the past few years, including his left knee in 2009 and his right knee in 2012.
Nadal visited a medical clinic in Vitoria, Spain to consult with his regular physician.
Although it is not clear when he will return to training, the Spaniard is expected to resume pre-season training in three weeks time and could potentially take part in the Abu Dhabi exhibition next season.
