Wexford defender Declan Ruth is facing a race against time to make Sunday week's All-Ireland senior hurling championship semi-final clash with Tipperary in Croke Park.
Ruth, who only took his place in last Sunday’s victory over Limerick following a late fitness test on a damaged hamstring, broke down during the second half, forcing his retrial.
Manager Tony Dempsey now believes Ruth has a real battle to make the semi-final.
"Declan has a big struggle ahead of him. He will be receiving intensive treatment and will be given every opportunity to prove his fitness. He is very, very doubtful," he said.
Dempsey’s injury worries do not end there.
Defender Colm Kehoe - who missed the quarter-final as the result of torn shoulder ligaments - is making slow progress.
"Colm participates in the running but is unable to play any hurling at present. We are keeping our fingers crossed that he will be available," said Dempsey.
However, he has better news regarding his other injury worries.
"Ryan Quigley’s hamstring should be okay. Daragh Ryan, who carried a hand injury into the quarter-final, came through but is now troubled with an ankle knock - but he should be fully fit in time."
Dempsey had his charges back in training on Tuesday evening but sees Tipperary as a new challenge.
"We may find it difficult to lift the side again. Tipperary will be warm favourites," he said.
