Apparently, Takayasu aggravated his leg injury sufficiently to pull out of the tournament on day 13. He already had his kachi-koshi, clearing his kadoban status, and wasn’t in yusho contention, so there wasn’t anything at stake other than pride.
Several dominos fall as a result. Goeido automatically gets his kachi-koshi by fusen tomorrow. And Hakuho gets none other than Endo on day 14. More to come tomorrow.
