Hull have signed hometown winger Tom Biggs from Bath rugby union club.
Biggs, 29, was born in Hull and was spotted by current England rugby union coach Stuart Lancaster while playing at Hymers College.
That led him in to a career in union, where he has since made 127 appearances, scoring 32 tries.
He has never played rugby league, but has been handed a three-year deal by the Airlie Birds.
Biggs said: “I think it is a big challenge in a sport that I’ve never played before, but it’s one that I’m really excited about and I’m feeling positive about working with the coaches moving forwards.
“Lee (Radford) played a few games for Hull RUFC and all the guys there gave him some great feedback so I’m really looking forward to working with him.
“Adam has outlined how ambitious he is as a person and where he wants to get the club going and I’m delighted to be given the opportunity to be part of that.”
Hull’s revolution under new coach Lee Radford includes a desire to instil local pride in the shirt.
Biggs has previously played for Leeds Tykes and Newcastle Falcons.
Coach Lee Radford said: “Tom looked very comfortable and competent playing in rugby union, but it was his enthusiasm about the prospect of leaving that to join Hull FC and the challenge in store that excited me.
“He could quite easily remain set on his current deal in union, but he was keen to have the opportunity to test himself in rugby league and play for us.
“He is a local lad and an FC supporter, which you can see means a lot to him, and we’re hoping we can nurture that enthusiasm to help him make a positive transition into our sport, which I am sure he will excel in.”
