Peni Terepo's NRL future at Parramatta is under a cloud, with the prop stood down after being convicted of careless driving in New Zealand.
The Eels on Friday also banned Terepo from participating in next week's Auckland Nines after only learning of last month's incident via New Zealand media reports on Friday.
"The club is extremely disappointed with Peni's behaviour and we regard what's taken place as extremely serious," Eels boss Bernie Gurr said.
"Upon learning of Peni's conviction, we have immediately alerted the NRL integrity unit this morning and emphasised that no club official was aware of this incident.
"Peni has been stood down from all official club duties, effective immediately, and will also not be considered for selection in our Auckland Nines squad."
The NZ Herald on Friday reported that Terepo, 25, had pleaded guilty to careless driving and refusing to give an alcohol test after a car crash in central Auckland.
The community magistrate said Terepo was "significantly intoxicated".
"It was some type of accident; police noted you did significant damage to your car and were thrown into the windscreen. It sounds like you were very lucky you weren't more hurt," the magistrate said.
Terepo was fined $500, ordered to pay $130 in court costs, and placed on a seven-month driving ban.
His future is likely to be decided once Eels officials meet Terepo following his arrival next week from New Zealand.
The revelations are the latest in a horror 12 months for Parramatta, including the salary-cap scandal and star Corey Norman's eight-game suspension for a sex video.
