NHL:Seán Óg Ó hAilpín and Kieran Murphy have become injury headaches for newly appointed Cork hurling manager Denis Walsh as the Rebels prepares to take on Kilkenny in this weekend's National Hurling League Division One encounter.
Ó hAilpín make his first appearance of the season in weekend's victory over Limerick but picked up a hamstring injury in the process. He is expected to be sidelined for at least one month.
Murphy was also forced off in the same game after he injured his shoulder in a clash with Brian Geary.
