Dan Gordon has been ruled out for Down ahead of their Ulster SFC replay against Tyrone in Newry on Saturday evening.
The powerful midfielder, who was man-of-the-match in the Healy Park draw, broke his thumb and will be sidelined for up to six weeks.
Yesterday's X-rays confirmed the break after Gordon took a heavy fall in the first half but played on against Mickey Harte's side.
Ambrose Rodgers is expected to fill in for Gordon.
Meanwhile Offaly are waiting on fitness news of their captain Kevin Brady ahead of Sunday's Leinster SHC semi-final against Kilkenny in Portlaoise.
The Coolderry halfback picked up a hamstring injury in training over the weekend and is extremely doubtful for the meeting with the All-Ireland champions.
Ger Healion is also struggling with a hand injury, but Joe Bergin and Rory Hanniffy are expected to return to the starting line-up.
