Rank-and-file grappler Daieisho sprang an upset against outright leader Terunofuji at the Autumn Grand Sumo Tournament on Monday, handing the Mongolian-born powerhouse his first loss as a yokozuna.
The newly promoted yokozuna dropped to 8-1 after failing to establish his favored belt grip and being forced out by No. 4 maegashira Daieisho in the final bout on Day 9 at Ryogoku Kokugikan.
Former sekiwake Daieisho (6-3) fought desperately to protect his belt at the jump before shoving the stunned title favorite off balance and over the edge.
