Jared Waerea-Hargreaves has escaped suspension for his foul-mouthed blow-up, with Sydney Roosters coach Trent Robinson claiming frustration at referee Gerard Sutton was justified.
Robinson argued his star prop was a target for officials, and it was only his expletive delivery that let him down on Saturday.
Waerea-Hargreaves was sin-binned for twice swearing at Sutton in the Roosters' 32-12 loss to Penrith, but the veteran forward was only fined $1800 after the Match Review Committee on Sunday handed him a grade one contrary conduct charge.
