Tyrone have been rocked by the news that Colm Cavanagh is likely to miss the entire McKenna Cup campaign with a wrist injury.
The Moy clubman sustained a fracture after an innocuous challenge while playing football at home.
An initial X-ray showed no damage but a subsequent MRI scan confirmed the injury.
Tyrone's defence of the McKenna Cup begins on Sunday with a home game against last year's runners-up Derry.
Cavanagh was one of the stars of last year's McKenna Cup run, although he sustained cracked ribs in the final win over Derry which ruled him out of the start of the National League campaign.
His midfield partner Mickey Murphy will also be unavailable as he is currently on a month-long holiday in Australia.
Forward Ronan McNabb is ruled out after undergoing surgery on a hip problem.
