Takanohana intends to break his silence and cooperate with an investigation into the assault of a wrestler that cost Mongolian grand champion Harumafuji his career, the Japan Sumo Association said Thursday.

But Takanohana, a former yokozuna on the JSA executive board, will only speak to the association's crisis management team once police have finished their investigation of the incident, which occurred last month during a regional tour in Tottori Prefecture.

A day after Harumafuji admitted to the assault and announced his retirement, Takanohana was called to Tokyo's Ryogoku Kokugikan for Thursday's association board meeting.
