Challenge Cup winners Hull have signed half-back Albert Kelly from Hull KR and tied centre Steve Michaels to a new deal.
Kelly, 25, travels the controversial but now well-trodden path across the city of Hull, keeping himself in Super League after Rovers were relegated.
Player of the year with KR in 2015, this year brought trouble for the former Gold Coast Titan, with his club leaving him out of their crucial and ultimately costly final games of the season on disciplinary grounds.
“It was pretty exciting seeing Hull go to Wembley and win the Challenge Cup. Some of my good mates were in there and to see them smiling and lifting the trophy is something I want to do as well,” Kelly said after agreeing a one-year deal.
“I think because the boys won it last year, we can go back-to-back if we put in performances each week.
“I think I might bring a bit more sting in attack and I think that’s a bit of excitement for the fans as well.
“I’m looking forward to getting stuck into training and have the boys show me the ropes and looking forward to wearing different colours.”
Hull FC head coach Lee Radford said: “As soon as we were notified that a player of his quality was available we decided to move and despite leaving Hull KR under clouded circumstances, it means he comes across the city in a very motivated mindset and with a firm focus on delivering his career best form.
“He is at a great age for a developing half back with his peak years in front of him and it is our job as a club and coaching staff to put everything in place for that to happen.”
Meanwhile, popular centre Michaels has agreed to extend his stay by a further 12 months.
Michaels became a cult hero to Hull’s fans but it appeared at one stage that he would be leaving East Yorkshire.
“I’m really happy to be on board for next season. I love the players, the fans and the club,” said the 29-year-old.
