Following the fracas that broke out in their defeat to Armagh last Sunday week, Tyrone will be without four key players for Sunday's visit of Kildare to Omagh.
The loss of Kieran McGeary, Peter Harte, Padraig Hampsey and Michael McKernan could be costly for the All-Ireland champions, who have taken just one point from a possible six in Division One to date - with ties against Donegal, Dublin, Mayo and Kerry to come.
Donegal were the last All-Ireland champs to be relegated from the top tier in 2013.
