Hull have signed Salford forward Josh Jones on a two-year deal from next season.
Jones, 26, has been an ever-present for the Red Devils this season, having joined them in 2016 after a brief stint with Premiership rugby union side Exeter Chiefs.
He said: “I’m really delighted to have signed for the club. It’s been a long couple of months of negotiations, so I’m really pleased that the deal has gone through with Hull.
“I know a couple of the players at the club. I spoke to Josh Griffin last night and I told him about the news. He was made up for me, so like I said, I can’t wait to get over there now and meet the rest of the team.
“I really liked the ambition of the club when I spoke to Lee [Radford], Adam [Pearson] and James [Clark]. Hull is a massive club that has a hunger for winning trophies and I’m equally as eager to win things.”
Jones started his career at St Helens, where he won the Super League Grand Final in 2014.
Hull coach Lee Radford said: “When you look at the calibre of other clubs that were in for Josh, it’s really pleasing that he has decided to join Hull FC because it shows where we are at.
“I think it’s a really, really strong signing and it’s a great start to our recruitment for next season. I’ve been a huge admirer of Josh for the last few years, so to finally have the deal done is a relief.”
