Derry manager Mickey Moran has an injury concern with ace forward Paddy Bradley ahead of Saturday's All-Ireland football quarter-final against Westmeath at Croke Park.
Bradley picked up a foot injury in training last week and has been receiving treatment since.
Moran is confident Bradley will be fit to start, and will need his team to be at its best against the Leinster champions.
Bradley is the key to their attack, having amassed a goal and 26 points in the qualifier wins over Wicklow, Cavan, Wexford and Limerick.
Kevin McCloy and Gerard O'Kane have both recovered from injury and are in line for selection.
