All Star Mark McHugh is a major doubt for the start of Donegal's NFL campaign with a pelvis injury.
McHugh (22) has not taken part in any field sessions since Jim McGuinness' side claimed the county's second All-Ireland title in September because of osteitis pubis, an inflammation of the pelvis experienced by many elite sportspeople.
McHugh remained on the sidelines for his college side IT Sligo's entire FBD Connacht League campaign but said that he still retains hope of featuring for Donegal in the coming weeks.
"I am not 100pc sure yet, but I am giving myself every chance," said the Kilcar clubman. "I have to just listen to what my doctors and physios say. Whatever they tell me, I'm going to have to keep to it.
"It's osteitis pubis; I have it now the last few months. I haven't played since the All-Ireland final. I have had scans and injections and stuff on it but it has just been there constantly since.
"I am just trying to clear it up before the start of the National League and for the Sigerson Cup with Sligo IT."
McHugh said he appreciates that time is running out if he intends to feature in Donegal's opening league match against Kildare at Croke Park on Saturday week.
"I haven't really trained on a field since the All-Ireland in September," he said. "I have done a few bits and pieces in the gym myself, but that's about it.
"I have been restricted from doing any running at all with it. That's all I can do at the minute, I am just waiting for a bit of good news to come."
