Horrific If True
One thing to keep in mind, the Japanese sumo press sometimes is given to speculation, so take this one with a grain of salt. From Yahoo Japan comes a quote from the Tagonoura stable master. He states that injured Yokozuna Kisenosato my join the summer tour later during the month of August.
This could indicate that it has been decided to have him “heal naturally”, and that Kisenosato feels like he needs to be taking care of his Yokozuna duties. With Hakuho (fresh from a Mongolian golf course) the only Yokozuna on he tour, Kisenosato may have decided that he can put up with more suffering for the cause of sumo.
Readers should form their own opinion, but after 2 back to back kyujo tournaments, I would rather have a great Kisenosato in 2018 than a malfunctioning, one-armed Yokozuna at Aki. Hopefully, someone from the Sumo Kyokai and or the YDC will urge him to get medical repairs before engaging in more public displays of sumo.
