Edwards met Myles and his agent in Sydney yesterday but the Queenslander has also been courted by Gold Coast and Parramatta.
Myles is contracted to the Roosters for next season but it has been reported that he will be allowed to leave Bondi if he can gain a long-term deal with a rival club.
Edwards said he had talked with Myles on the recommendation of incoming coach Wayne Bennett.
One option is Snowden, who has been linked with Newcastle since Nathan Tinkler contacted him three months ago and persuaded him not to re-sign with the Sharks.
It appeared certain Snowden would return to his home-town club once Tinkler’s privatisation bid was approved but the Sharks have since responded with a far more lucrative deal.
Edwards said negotiations with Snowden had been put on hold to allow the Lakes United junior to concentrate on making his Test debut tomorrow night.
But he would not rule out the possibility of bolstering Newcastle’s pack with both Snowden and Myles next year.
Boyd has won premierships under Bennett at Brisbane and the Dragons and recently stated his desire to continue playing for the master coach.
But he is understood to be considering an offer from the Gold Coast, so that he can be closer to his grandmother, who lives on the holiday strip.
Edwards said the Knights were slowly piecing together next season’s likely roster in consultation with Bennett.
Veteran Adam MacDougall is expected to retire at the end of the season.
