Tamou has admitted to the club that he had several drinks earlier in the night and he will not contest the charge.
“The Cowboys are extremely disappointed, as is James, in these events,” CEO Peter Jourdain said.
“James is taking responsibility for his actions and is very remorseful that he has put himself in this position.
“This is his first offence. He knows it is a serious one and that he will have to pay a penalty.”
The matter will be heard in the Townsville Magistrates Court at a later date.
