Tipperary corner-back Cathal Barrett is a doubt for Sunday week's Allianz Hurling League semi-final against Waterford after injuring his shoulder in training.
The 2014 Young Hurler of the Year sustained the injury during a warm weather training camp in Spain during the week and will have an MRI scan on his return to assess the extent of the damage.
Seamus Callanan will definitely miss the semi-final after deciding not to make any further appeal against the red card he was shown during the quarter-final win over Offaly.
The Drom & Inch forward was sent off for an off-the-ball strike shortly after half-time in that game and subsequently had a one-game suspension confirmed by the Central Hearings Committee.
Tipperary had been considering an appeal to the Central Appeals Committee but have now accepted their star forward will miss the semi-final.

Both games take place on Saturday 18 April. Dublin will face Munster champions Tipperary in O'Connor Park, Tullamore at 4pm, with Tyrone and Roscommon facing off in Markievicz Park, Sligo at 6pm.
Meanwhile, Shay McGuigan has revealed that frustration with a lack of playing opportunities was behind his decision to quit the Tyrone panel earlier this week.
Patrick McNeice, Dwayne Quinn and Emmett McKenna also left Mickey Harte's panel following the draw against Kerry that condemned the Red Hands to Division 2 football next season.
“It’s pure frustration,” McGuigan told Gaelic Life. "You’re coming home every week when the team is named and you’re not on it.
"It’s the same boys every week, they’re getting their chances and you’re not getting yours. I was putting in the same work as they were but wasn’t getting out on the field.
“I hung on and hung on. I was debating leaving after the Dublin game, but I hung on because I thought I was bound to get a chance, and when I got it I was going to take it.
“But then the Cork game came and went and there was still nothing. It was really starting to get to me, but there were only a couple of games left so I thought I’d wait and see how things panned out. The Donegal game I thought I’d definitely get a chance, because we were struggling, yet I still didn’t get the nod.
“By that stage I had already decided that if I didn’t play against Kerry then I was going, because if you’re not playing in the league then you’re hardly going to be part of the plans for the championship, so I obviously wasn’t part of Mickey’s plans for this year.”
