Shaun Lunt has stepped down as captain of Hull KR following his health scare.
The 31-year-old former Huddersfield and Leeds hooker, who has led Rovers for the last two years, spent three weeks in hospital towards the end of the 2018 season with what turned out to be an abscess on his spine.
Lunt will miss the start of the new season and announced his decision to relinquish the captaincy as he focuses on his rehabilitation.
"I thought that with everything that I went through last year, I've got to concentrate on my health," he said.
"I've got a long way to go to get back to 100 per cent. In terms of captaincy and the added pressure I feel like I didn't need it.
"I need to be selfish and worry about myself and make sure that my health is 100 per cent.
"Another thing is that I haven't really focused on pre-season just yet - I don't think I am in a position to have earned it. The lads have worked hard all pre-season so I don't think I deserved it this year.
"It was a great honour to help lead this club and something I have really cherished these last two seasons."
Former Wigan and England forward Joel Tomkins has been appointed as his replacement.
The 31-year-old Tomkins, who has made just nine appearances for the Robins since joining them from Wigan last summer, was elected to the role following a poll of the players.
"It's a massive privilege to be given the job, especially as the boys voted for it," said Tomkins.
"That really means a lot to me. I've worked really hard since I've come here to make a good impression and this is a big reward for that.
"Obviously Shaun has had a few issues towards the back end of last season and he hasn't really done much so far this pre-season so he decided to step down but he has still got a massive role to play.
"We have a big group of senior boys so it is not just down to me, we have a big group of leaders here."
