Yokozuna Harumafuji has undergone right elbow surgery, his Isegahama stable revealed on Wednesday.
The Mongolian yokozuna had the procedure on Tuesday to remove detached cartilage from the elbow but is not expected to miss July's Nagoya Grand Sumo Tournament.
On Sunday, Harumafuji wrapped up the summer tourney in Tokyo with a superb win over fellow yokozuna and countryman Hakuho to finish with an 11-4 record.
"Being unable to extend his right arm, he was unable to shove and thrust — things he is really good at," Isegahama said. "I think from this point on, he will become strong again."
