Leeds Rhinos hooker Paul Aiton has been ruled out for the next three months of the season.
The 28-year-old Papa New Guinea international is due to undergo a course of prescribed medication to treat the medical condition that has seen him miss the past two weeks.
"I'm so enjoying being part of the Rhinos team and really disappointed I will be out for so long. But, I'll do all I have to and be back raring to go," Aiton told the club's official website.
Aiton joined Leeds from Wakefield Trinity Wildcats in the summer.
