A remorseful James Tamou is facing a ban that could end his NRL career following his expletive-laden abuse of referee Ben Cummins.
The Wests Tigers veteran admitted he let his frustrations get the better of him when sin-binned by Cummins late in his team's record-breaking 72-6 loss to the Sydney Roosters on Saturday night.
The 304-gamer's worst fears were realised on Sunday morning when he was handed a grade-three contrary conduct charge for the incident.
