The former Bradford Bulls player has had a promising start to his Airlie Birds career, scoring ten tries in 14 appearances for the senior side including a stunning hat-trick against Castleford Tigers in last year’s Challenge Cup.
Having featured for the club’s Under 23s in 2016, Naughton made his first Super League appearance of the season against Wakefield Wildcats. He got over the whitewash in the 33rd minute to help the Black and Whites to a 22-4 victory.
“I’m really pleased. I think he has a great long-term future at the club,” Radford said.
“There was interest in him from elsewhere but the fact he wanted to stay is a credit to the group and a credit to Hull FC.
“We want to find him a starting spot and fulfil his potential. He has a good strike rate and can cover the outside backs, either at full-back or on the wing. He’s still very young and he has a lot of progression left in his game.”
Naughton said he is really happy to be staying at the club.
“I love been here so when Lee and Motu [Tony] said they wanted me to stay for at least the next few years I was delighted,” he said.
“My main focus now is cementing a place in the side and playing first-grade regularly.”
