Hayne stunned his former club Parramatta in October when he announced he was turning his back on the sport he grew up playing and a potential multi-million dollar contract with the Eels to pursue a career in the NFL.

He left Australia within a week of making the announcement and has been busy training in southern California as he looks to defy the odds and break into the billion-dollar sport.

US website the National Football Post — a forum where professional football insiders break news and provide information and insight — first reported that Hayne had visited the Seahawks on Tuesday, a day after he had visited the 49ers. The Seattle Times picked up the report and blogged: “Hayne will hold some workouts and then maybe sign with an NFL team after the season, when rosters can expand from their current 53 (plus practice squad, etc) to the 90 that is allowed for training camp.

“What is also likely is that you will hear about Hayne visiting lots of other teams.

“So for now, while it’s interesting that Hayne paid Seattle a visit, I’d hold off anointing him a Seahawk.’’

Hayne’s Australian manager, Wayne Beavis, said the former Eels fullback was poised to sign with a US agent and that there were many options open to him at the moment.

“He’s going good,’’ Beavis said. “That was the plan (to meet the franchises) and he’s got an agent over there now that he’s dealing with.

“(Whether he returns home before Christmas) depends on what he does. It depends on if he gets picked up, it depends on if he goes into a practice squad, into a workout squad or into a team. There’s 14 different contingencies and everyone’s second guessing.

“It’s up to the clubs.’’

The former NSW Blues fullback has already been linked with the Seahawks — who won this year’s Super Bowl — after he met officials during a 10-day study trip to the US in September.

Seattle coach Pete Carroll has also spoken about Hayne — ­although it has been suggested he was half-joking — after describing him as an incredible athlete and the prospects of recruiting players from the NRL as exciting.

There have also been reports Hayne has already received a preliminary offer to train and trial with the Detroit Lions.

UTS chief executive Matt Steel — the boss of a club that Hayne once trialled with and which competes in the NSW competition — said he heard that Hayne had been training the house down in the US amid reports he had bulked up significantly.

Before he left for the US, the former Dally M winner indicated that he saw his future in the NFL as a running back as the position shared common traits with his NRL role as a fullback.

Steel said the big test would come in February when Hayne fronts up for the NFL Scouting Combine, a week-long event where college football players perform physical and mental tests for NFL coaches, general managers, and scouts.

“It’s fantastic these franchises are showing interest in him and trialling him because he would be the X-factor to them,’’ Steel said.

“If they could pick someone up like that and spend a bit of time with them he could be exactly what they’re looking for.

“And getting an open door like that and being able to see the way they operate ... is massive for him.’’
