The North Queensland Cowboys playmaker Johnathan Thurston will not face National Rugby League sanctions after his outburst following their controversial 20-18 play-off loss to Cronulla.
The Cowboys were on the receiving end of a seven-tackle try after referees Matt Cecchin and Henry Perenara getting their tackle count wrong.
Thurston claimed after the match that New South Wales' lack of State of Origin success was filtering through to retribution in NRL games, with the Cowboys on the receiving end of poor refereeing decisions in two consecutive years of finals.
The NRL's head of football Todd Greenberg says no action will be taken against Thurston for his remarks.
Referees Cechin and Perenara were both dropped for the second week of NRL finals.
