Westmeath have suffered a pre-season blow, after midfielder David Duffy tore a hamstring in a challenge match at the weekend.
Duffy is expected to be out for at least four weeks, further depleting manager Pat Flanagan's playing resources for Sunday's opening game in the O'Byrne Cup.
Martin Flanagan, Damien Healy, John Keane and Derek Heavin have all retired from inter-county football.
Meanwhile, Mayo attacker Conor Mortimer could miss the entire season if he decides to undergo surgery to repair a long-standing knee problem.
He tore the medial ligament injury in his left knee before Christmas and surgery may be the only option.
