The threat of the release of more explicit videos has seen Dylan Napa and his manager Steve Gillis reportedly meet with lawyers on Monday.
Desperate to stop the leak of videos, Napa and his team met in Sydney to come up with a damage control strategy.
The Sydney Morning Herald reported the Napa videos were posted "four to five years" ago on a private WhatsApp group involving other players.
But in what appears to be an act of revenge porn, a third tape has reportedly surfaced with Napa referring to himself as "Big Papi", as he was in the first video released last week.
At the weekend, the NRL Memes page on Facebook promised to share a second video of the star "doing a lot of weird s***, including giving himself a prostate exam".
On Saturday, a second video, which has been viewed by news.com.au, emerged and it began by showing a fully clothed person shadow boxing before the camera pans to a near naked man, allegedly Napa, touching himself.
The Sydney Morning Herald reports Napa told the Bulldogs who took the videos but won't reveal the person's identity.
Wide World of Sports reported the first clip was filmed by a former teammate during a trip by his previous club the Roosters to the United States after they won the 2013 Grand Final.
Another unnamed player, with whom Napa had a falling out, is the person responsible for leaking it, the website claims.
Napa has recently started a three-year contract at the Bulldogs, with the club releasing its second statement surrounding the issue in as many days.
"The club is aware of a further social media video that has emerged today that was taken several years ago," the statement read.
"The club can confirm that Dylan Napa has received legal representation and advice from senior legal council, as well as made contact with the NSW Police. The club is supportive of Dylan and is providing welfare support."
