Durban: The organisers of Super Rugby are investigating a complaint made against Waratahs coach Michael Cheika after the side's spiteful clash with the Sharks on Saturday.

South African broadcaster Super Sport has alleged to SANZAR that Cheika had a brief verbal confrontation with a camera operator during the match at Kings Park Stadium.

Cheika had left the coaches box and walked down to the pitch to talk to defence coach Nathan Grey, who was running the water during the game.

A Super Sport spokesman confirmed on Tuesday that the company had lodged a complaint with match commissioner Piet Strydom, who in turn conveyed it to SANZAR.
