Cork hurling manager Kieran Kingston said corner-back Colm Spillane's torn cruciate injury was a "devastating" blow for the Rebels, as the 22-year-old was ruled out for the rest of the season.
Cork fell short against Waterford in their Allianz Hurling League Division 1A clash last Saturday, going down 0-20 to 1-14 at Pairc Ui Rinn.
That defeat was compounded by Kingston's injury, sustained in the 48th minute, the full extent of which was confirmed after a scan on Monday evening.
“The news is devastating, firstly for the player himself and it is a huge blow for us as a management team," Kingston told The Evening Echo.
"Colm went off injured in the second half last Saturday night and, whilst we were hoping the injury was not too serious, the scan has revealed the worst. He’s a big loss to our plans going forward because he was going very well.
“The injury is similar to the one Christopher Joyce sustained last year and all we can do now is give Colm every support during his stay on the sideline and welcome him back when the time comes again. He’s only 22 so he’s young enough to come back as good and stronger than ever."
Kingston's team were defeated 1-27 to 1-21 by Galway in their league opener. They next face Dublin on Saturday week.
