Hull KR centre Sean Gleeson may lose an eye after he was attacked outside a nightclub.
The 26-year-old was punched in the face a number of times following a row with three men in Wigan in the early hours of Sunday.
He suffered serious injuries to his eye and eye socket and was taken to hospital, where he remains.
Gleeson became involved in a fight with one of the men outside Ibiza Bar in King Street and the others joined in before they left the Rovers player in the road and ran away.
Gleeson signed for Rovers last year but has yet to play this season following a string of injury problems.
