NAGOYA - Grand champions Onosato and Hoshoryu are set to return from injury, while Ukrainian star Aonishiki will begin his battle for re-promotion to ozeki when the 15-day Nagoya Grand Sumo Tournament opens Sunday at IG Arena.

The 22-year-old Aonishiki faces a pivotal test after sitting out the entire Summer Grand Sumo Tournament in May with ankle trouble and dropping from ozeki to the third-highest rank of sekiwake.
