The RFL are to investigate after Catalan Dragons full-back Clint Greenshields described a referee as "retarded".
Official Ben Thaler came under fire from Greenshields on Twitter following his performance in Friday night's Super League game at Leeds, one the Dragons lost 34-18.Greenshields blasted Thaler in a foul-mouthed outburst and the RFL were quick to act, confirming on Saturday morning that a probe has been launched, one which could lead to a ban or a fine for the player.
Dragons coach Trent Robinson was caught unaware by the comments during the post-match press conference.
He said: "I haven't seen any of that stuff. There's always a danger with those sort of comments. It's tough watching - you get emotional.
"I don't think Ben is retarded."
