Sean Powter, Donncha O'Connor and Colm O'Neill are all in danger of missing Cork's Munster SFC final meeting with Kerry.
Last year's Young Footballer of the Year nominee Powter suffered a hamstring tear during the league clash with Tipperary in late January. He has resumed training but suffered a setback in a challenge match against Roscommon last week.
O'Neill, meanwhile, sustained damaged knee cartilage during the comprehensive provincial semi-final defeat of Tipperary last month and underwent minor surgery. He has a chance of featuring at Pairc Ui Chaoimh on June 23rd but, as with Powter, is in a race against time.
And O'Connor, who missed the Tipp game, is struggling to see off a niggly hamstring problem, while Brian O'Driscoll (hamstring) has made a full recovery and is available.
