Kerry may hold some of their biggest names in reserve for their opening championship clash against Tipperary this weekend.
Doubts remain over whether Footballer of the Year James O'Donoghue, Colm Cooper and David Moran will start for the All-Ireland champions in Thurles. Young Footballer of the Year Paul Murphy has already been ruled out with a shoulder injury.
O'Donoghue dismissed injury concerns surrounding him two weeks ago as he continues to rehabilitate from a shoulder operation he underwent in November.
Cooper has only played a handful of minutes for Kerry against Tyrone in the league since he returned from his cruciate rupture, while Moran is thought to be still carrying a shoulder injury which he sustained in a club game recently and may not start either.
Last year's joint captain Kieran O'Leary has sustained a suspected ruptured Achilles which could potentially leave him out of action for up to six months. He is due to have a scan to determine the extent of his injury. Kerry manager Eamonn Fitzmaurice is due to give an update on the injuries at a briefing on Thursday night.
Kerry returned from a warm-weather training camp in Portugal over the weekend. Off the field, the county has been reaping benefits of being All-Ireland champions with a fundraising drive in the USA which is expected to yield in the region of €1m for the development of a new training facility.
