Hull KR centre Sean Gleeson has admitted that he thought he might be forced to retire during his injury lay-off earlier this season.
Gleeson, 25, has only made two Super League appearances this year
because of a back injury.
He is in his first season with the Robins
after joining from Salford.
"With it being your back you don't know how serious it is and I thought I was going to have to stop playing," he told BBC Radio Humberside.
"I've been through a torrid time, it's been the worst thing in my career. I didn't think it was ever going to get better.
"Thankfully I'm back playing and in a few more games I'll be at full fitness and ready to go. You can train all you want but game fitness is a different thing.
"The coaches have been brilliant with me and so have all the lads. Everyone's been really helpful."
Craig Sandercock's side, who face Wigan on Friday looking to avenge their
thumping 84-6 loss
earlier this season, are currently sixth in the Super League table.
