Midfielder Seamus O'Shea is doubtful for Mayo's All-Ireland quarter-final showdown with either Donegal or Galway after picking up a groin injury in Sunday's Connacht final romp over Sligo.
Mayo football bosses Noel Connelly and Pat Holmes face an anxious wait to see if the oldest of the three O'Shea brothers will recover in time for the quarter-final in less than three weeks.
O'Shea was forced to exit the fray 24 minutes into Sunday's rout of Sligo, but the Breaffy midfielder is hopeful it will be a short-term problem.
"It was in a tackle and whatever way I twisted or turned, I gave it a bit of a pull but hopefully it will be all right," said the 28-year-old powerhouse.
"I gave my groin a bit of a pull. I am not too sure how bad it is. We will see what the medical team says and hopefully it won't take too long to recover."
With Tom Parsons also in fine form alongside him and Barry Moran impressing after he replaced him, O'Shea knows Mayo are spoilt for choice in midfield, so he'll be keen to be fit for the Croke Park date in the last eight.
"We will tear back into training now on Tuesday or Wednesday night," he said.
O'Shea was delighted with Mayo's five-in-a-row and took issue with those who devalue the achievement.
"It is great. Five-in-a-row hasn't been done for 50-odd years in Connacht," he said. "A lot of provincial titles have got a bit of battering in the last while, but it is not easy to win these.
"We were pushed very hard by Galway in the semi-final and we have seen how they have gone on. It is not easy to win them so we are delighted to win five-in-a-row - it is a big achievement."
