Meanwhile, Smith's switch to rugby union could happen before the end of the current Super League season.
The Yorkshire Evening Post revealed yesterday that Wasps are keen to sign Smith, whose Rhinos contract expires at the end of the year. The Guinness Premiership outfit are understood to want Smith in their squad in time for pre-season training, in June.
Super League's anti-tampering rules don't apply to union clubs, so Wasps are free to approach Smith at any time.
Should a deal be confirmed, Rhinos would have to decide whether to release the player early, in mid-season – as Bradford Bulls did with Lesley Vainikolo and Shontayne Hape, to Gloucester and Bath rugby union clubs.
