Wrestling coaches cop ban for Rio protest

World Wrestling has banned Mongolian coaches Byambarinchen Bayaraa and Tserenbaatar Tsogtbayar for three years for their bizarre protest during the Olympics.

The pair responded to Mandakhnaran Ganzorig's controversial defeat to Uzbekistan's Ikhtiyor Navruzov in his under-65kg bronze medal match by first throwing their shoes at the match judge and then stomping onto the mat and tearing their clothes off.

An investigation was opened into their conduct and they have now been suspended. The Mongolian federation will face no ban from competition but has been fined 50,000 Swiss Francs ($A67,577).

Ganzorig had been leading 7-6 with 18 seconds remaining when he began to dance around Navruzov in celebration. He was penalised for passivity, bringing the scores level.

That prompted the coaches' protest, which in turn brought a second caution to hand Navruzov an 8-7 win.
