A few Day 7 results

[Yugo Yodogawa <yyy@soda.berkeley.edu>]

Ok, I don't know much about Day 7, but I heard a couple of results over the 
phone.

Wakanohana dropped out of the tournament, I think because of a foot injury.

Kotonishiki got his first kuro-boshi after Kaio beat him; unfortunately, Kaio,
who has been very impressive this basho, hurt his back and may be out of
the tournament, although I'm not sure on this.

Takanonami lost to Kotonowaka; Takanohana, Musashimaru, and Akebono all won
their respective bouts.

Hmm that's all I know at this point.  At any rate, there are no longer any
undefeated rikishi, and several with 1 loss.
