Mongolian-born sumo wrestler Kyokutenho will be suspended from the upcoming Summer Grand Sumo Tournament for causing a traffic accident, the Japan Sumo Association said Monday.

The executive committee of the JSA, which forbids its wrestlers from driving, also imposed a 30 percent salary reduction for three months each on Kyokutenho and his stable master, Oshima, as part of its punitive action.

Kyokutenho ran into the back of a car waiting at a traffic signal at a junction in Tokyo's Nakano Ward on April 28, causing minor injuries to the driver. The veteran made his professional sumo debut in 1992.
