TIPPERARY'S Seamus Callanan is bracing himself for another spell on the sidelines after sustaining hamstring damage against Dublin in last Sunday's senior hurling challenge.
Premier County medical staff are assessing the situation, but early indications are that Callanan (24) – who missed the 2011 and 2012 National League campaigns through injury – may have suffered a significant muscle tear.
The Drom and Inch forward marked his return for Tipperary with a fine haul of 0-11 against Offaly in a challenge match in Templemore nine days ago.
And Callanan had notched seven points before he came off early in the second half against the Dubs.
He would not have featured for Tipperary against Limerick in next Sunday's Waterford Crystal Cup quarter-final as he was due to line out for Limerick IT in their clash with Kerry.
John O'Keeffe is also ruled out due to college commitments with LIT and Tipp manager Eamon O'Shea will also have to plan without University of a Limerick pair Paddy Stapleton and Adrian Ryan.
Defender Tomas Hamill is expected to feature for Waterford IT against Cork and both Sean Curran and Noel McGrath are also ineligible.
O'Shea is therefore planning without seven players in total, including Callanan, due to college commitments ahead of what will be an early dress rehearsal ahead of the Munster SHC semi-final between Limerick and Tipperary on June 9.
