Hull KR centre Sean Gleeson has been forced to retire because of a serious eye injury he suffered in an attack outside a Wigan nightclub.
The 26-year-old sustained injuries to his eye and eye socket in the incident in March.
The former Ireland international then broke his leg at the club's winter training camp.
He told the club website: "It is with regret that I have made the decision to retire from this great sport.
"I would like to say a big thank you to the Hull KR fans for welcoming me to the club and to Hull, where I have made so many friends in and out of rugby league.
"Lastly, I would like to thank Craig Sandercock for believing in me, giving me the chance to play for a club with such great heritage and for standing by me through the injuries that I sustained."
Gleeson also played for Wigan, Widnes, Wakefield and Salford during his career.
