Team captain Michael O'Shea is the biggest injury worry in the Clare camp ahead of their Munster SFC quarter-final encounter with Waterford on Sunday (Cusack Park, throw-in 3.30pm).
O'Shea picked up a calf injury in the Banner's recent challenge match defeat to Tipperary. He has been on crutches and paid a visit last week to the ice chambers in Wexford in a bid to speed up his recovery.
Defenders Niall Considine and Darragh Kelly, who was injured in the Tipp game, are also in danger of missing the renewal of rivalries with Waterford.
The Deise shocked Clare in last year's championship, beating them by 1-6 to 0-7 for their first SFC win in 19 years.
Clare goalkeeper Joe Hayes sat out training on Tuesday but is expected to be fit for the game.
Owing to those injuries, Banner boss Frank O'Doherty has delayed naming his team for the Munster quarter-final and if O'Shea does not make it, Doonbeg clubman Conor Whelan will skipper the side.
Clare, winners of the McGrath Cup earlier this year, fell to a six-point defeat to Waterford when the sides met in March in NFL Division 4.
The Banner men were recently joined for a training session by Munster and Ireland prop Marcus Horan, who conducted part of the session and passed on some advice to O'Doherty's charges.
Clare selector and the county's 1992 Munster championship-winning goalkeeper James Hanrahan set up Horan's visit and the rugby star could return for more sessions later in the summer.
