SLEACHT Néill are sweating on the fitness of skipper Paudie Cassidy for their Derry quarter-final clash with Lavey at Owenbeg on Sunday. Better will be required to beat Lavey on Sunday, warns the former Down star. “I don’t think anybody in Sleacht Neil is under any illusions that we’ll have to bring our best performance of the year to beat Lavey. Mark Doran says Sleacht Neil need to produce their best performance this season to beat Lavey. I just hope Sleacht Neil are still there.”
