Kerry boss Peter Keane looks set to be without injured defender Brian Ó Beaglaoich over the coming weeks.
It is understood that the An Ghaeltacht clubman picked up a leg injury in their opening Allianz FL Division 1 draw with Dublin which will see him sidelined until March at the earliest.
As a result, Ó Beaglaoich was substituted before half-time against the Dubs and played no part last weekend in their defeat of Galway as Keane struggled for defensive options.
However, regular starters Tadhg Morley and Tom O'Sullivan are expected to come into the mix for their trip to Omagh this Sunday against Tyrone as the Kingdom bid to maintain their unbeaten record in this year's league.
There is also some doubt about James O'Donoghue's participation this weekend after the 2014 Footballer of the Year was taken off at half-time last weekend against Galway. It is believed that O'Donoghue may have picked up a knock and could be rested given his injury woes in recent seasons.
Meanwhile, Wexford hurling boss Davy Fitzgerald has been boosted by the return of joint-captains Matt O'Hanlon and Lee Chin.
Both returned to training in recent weeks after being sidelined through injury and could feature this Sunday as Wexford take on Waterford in a challenge game in Ferns.
Should the pair come through unscathed, they may feature as the Leinster champions face Kilkenny in Wexford Park on Sunday week.
Elsewhere, Galway hurling manager Shane O'Neill has been hit with a setback as All-Ireland winner Joseph Cooney has confirmed he will not be returning home from Australia to re-join the panel for this year's action.
