A fractured ankle will keep Kerry defender Killian Young out of next Sunday's All-Ireland SFC semi-final against Dublin at Croke Park.
Young sustained the injury in an internal training match yesterday during the Kerry panel's trip to the Fota Island Resort facility in Cork, and an ambulance brought him to hospital shortly afterwards.
A statement from Kerry GAA confirmed: "Kerry defender Killian Young sustained a fractured ankle in an internal training match. He will be meeting a consultant early next week."
The Renard clubman has been ever present at centre-back for the Kingdom this summer, including the provincial wins over Tipperary, Waterford and Cork and the recent All-Ireland quarter-final victory against Cavan.
Losing a defender of Young's calibre is a huge blow for the Munster champions who will be facing a Dublin team that has scored 8-69 in their four Championship outings to date.
Eoin Brosnan, who is Kerry's captain this season, and St. Michael's Foilmore clubman Mark Griffin - a Championship debutant at full-back against Cork last month - head the list of possible replacements for Young.
