The referee is never the most popular person on a soccer pitch, but the man in charge of Tuesday's J. League clash between Oita Trinita and FC Tokyo certainly didn't do himself any favors.

Yuichi Nishimura, a full-time, FIFA-level official, allegedly told Oita player Taikai Uemoto to "die" as the defender remonstrated over one of Nishimura's decisions.

The JFA's disciplinary committee is currently investigating the matter, and Nishimura will be in big trouble if he is indeed judged to have used those words.
