Eoin Doyle is expected to miss Kildare's All-Ireland SFC Round 4B qualifier against Armagh on July 29 due to thumb surgery.
The captain and centre back suffered a broken thumb in the build-up to yesterday's Leinster SFC final loss to Dublin and is having it operated on this morning.
"He'll be in for surgery (Monday) morning," Kildare manager Cian O'Neill revealed.
"It's a measure of the man. There was no way he wasn't going to be playing today. Eoin broke his thumb last week and he just felt he could get through. We felt he could get through along with him and he played as much as he could and put in a real stellar performance, considering.
"There were obviously some parts of his game that he couldn't execute but I think that was far superseded by the brilliant things he did in marshalling that defence for large periods. It's most likely he won't be available in two weeks time but we'll wait and see."
The Lilywhites are also facing the prospect of being without midfielder Kevin Feely after he picked up his third black card of the season against Dublin, which has earned him a one-match suspension.
