Released by London Broncos at the end of last season, the Scotland winger has been training on his own since the World Cup, in which he played all four games for the Bravehearts and scored tries against the USA and in their quarter-final defeat by New Zealand.
"I'm keeping fit, doing my own stuff, but it's hard to keep that going to the level required," said the 23-year-old from Salford.
"I've had some inquiries from a couple of Championship clubs but none of them were right for me as this stage of my career. I would love to play in Super League again but wouldn't rule anything out."
Hurst played rugby union for England Under-16s, Sale, Fylde and Sedgley Park as well as league for Salford and Swinton.
He started last season by making his Super League debut for London Broncos, having impressed coach Tony Rea during his Scotland performances in last year's European Cup, but lost his place in the struggling side and went to partner club London Skolars, where he played in the Northern Bowl Final.
Having moved back to the Manchester area, Hurst is coaching sport in after-school clubs and waiting for a call to return to full-time rugby.
