Donegal's Eoghan Bán Gallagher is set to miss the Super 8 clash with Kerry at Croke Park on Sunday.
Gallagher reportedly suffered a leg injury in training last night.
Declan Bonner's side started their Super 8's campaign with a win over Meath last weekend.
It is unclear yet if he will be back in time for Donegal’s meeting with Mayo on the August Bank Holiday weekend.
