After the 2015 Japanese National Figure Skating Championships, two of Japan's biggest names in figure skating have put pause on Japan's roster for the remainder of the season.
Reigning Olympic champion Yuzuru Hanyu will be hospitalized for two weeks and off the ice for one month after having surgery for a bladder problem, reported Japan Times.
"I have felt some pain since the Grand Prix Final and spoke to my doctor about it," Hanyu said in a statement on Tuesday. "I was advised to have an examination to determine the extent of the problem."
The Japan Skating Federation confirmed that the issue was on Yuzuru Hanyu's urachus, a fibrous remnant of the allantois, which is a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord.
Meanwhile, reigning world silver medalist Tatsuki Machida announced his retirement shortly after placing fifth at the Japanese Nationals this past week.
According to CBC, Machida will be retiring to pursue a graduate degree in Sport Sciences at a university in Tokyo.
"He had the entrance exam to Waseda Unviersity right before Skat America and got accepted on the day of Skater America's short program," commented Takashi Takemoto on Facebook. "He has been wanting to pursue his study."
"Too bad they didn't realize he was serious about his study. It seems he wanted to concentrate on his thesis and cancel the Grand Prix Final, but the Federation didn't let him. Perhaps it made him feel like having to choose either skating or study. He is one of the few people who could accomplish both-what a loss."
