Star Parramatta half-back Mitchell Moses says he was subject to repeated death threats in the lead-up to his side's NRL clash with the Warriors.
The 27-year-old said his family had copped threatening text messages and phone calls aimed at him "non-stop", to the point where he received a police escort while entering and exiting the stadium for Friday night's match.
Fans were said to be subjected to hand-held metal detector searches. with security measures stepped up as a result.
Speaking on Saturday morning, Moses revealed he had gone to the NRL for support given the seriousness of the situation.
"It was a bit tough, a bit tough for my family," he told Triple M.
"I just had a couple of threats heading towards my family about me and about the game. They put pretty much a threat on the game and myself.
"We cleared it up with the NRL and they looked after me and escorted me into the game and looked after me ... they handled the situation pretty well and I felt pretty safe."
NRL chief executive Andrew Abdo said the threats were "very concerning", and the league quickly worked with authorities to put extra protections in place.
"We have an integrity unit that has great relationships with the clubs and the police," Abdo told ABC Sport.
"In this particular case, as soon as we got intelligence of this we worked together with NSW Police, with the stadium and with the club to ensure there was extra security and protection.
"We take it very seriously, and we have a team working around the clock on gathering intelligence and as soon as we get anything we have to act on, we do that."
Moses said the individuals behind the threats had not been identified, with police continuing investigations.
With his family on the receiving end of the threats, he admitted it had been tough to focus on football.
"It was pretty tough, the whole week was a bit like that and that uncertainty on what's going to happen," he said.
"You don't know what's gonna happen, it's a pretty scary thing."
