The Japan Sumo Association has decided to cancel the upcoming Spring Grand Sumo Tournament over the match-fixing scandal that has plunged the sport into what may be its biggest crisis ever, sources said Saturday.

The 15-day tournament in Osaka was scheduled to start March 13. The association planned to formally announce the decision at an emergency board meeting Sunday, the sources said.

"If we go ahead with the tournament in the current circumstances, it will just create more turmoil and trouble for everyone," a JSA board member said. "The JSA executives made the call. Even the summer tournament could be in doubt depending on the outcome of the investigations."
