An overhand right followed by a big left hook dropped Tsuyoshi to the mat, where he would receive not one, but two soccer kicks to the head. The referee mercifully stepped in, giving Shoji the KO win at 0:18 of Round 1.
With Sentoryu making only a slightly better debut, I think its safe to say that Sumo Wrestlers should keep their diapers on and stay in the sport they came from.
