Yokozuna Hakuho remained undefeated in his comeback from injury at the Nagoya Grand Sumo Tournament on Monday, using his polished grappling technique to topple rank-and-file opponent Endo.

Ozeki Terunofuji, who is bidding for promotion to yokozuna, was also victorious on Day 2 at Dolphin's Arena, but the action inside the ring was overshadowed by injury concerns for ozeki Takakeisho, who appeared to be hurt during his upset loss to No. 2 maegashira Ichinojo.

The winner of a record 44 top-level championships, Hakuho has staked his career on his results at the current 15-day meet after missing all or part of the past six tournaments and undergoing knee surgery in March.
