Chris Crummey faces a major race against time to play a part in Dublin's forthcoming Leinster SHC campaign.
Mattie Kenny revealed after Sunday's final league outing in Ennis against Clare that last year's captain had undergone corrective surgery on his shoulder last week on due to the injury he suffered against Wexford in Croke Park.
Dublin's provincial opener in just under ten weeks away - against Kilkenny in Parnell Park on May 10th.
"It could be 12 or 14 weeks," said team mate Paddy Smyth of Crummey's date of return. "It's just week on week. Seeing how it goes."
Conal Keaney has yet to resume full training after having a metal plate removed from his shoulder last week but is expected to return soon.
Smyth admitted Dublin were "disappointed" not to make the knock-out stages of this year league but maintained that their priority this spring was developing their panel for the championship.
"We had over 30 lads who got game time," the Clontarf defender outlined. "So from that aspect, that should benefit us going forward into summer."
It leaves Kenny with a clear month of March to train the squad before they return to their clubs for two rounds of club championship in April.
Dublin endured a difficult league campaign with injuries, with no fewer than four players suffering hamstring strains in a single match against Laois in Parnell Park.
"That showed we were training hard up until the week of the game", Smyth explained.
"This is what? Ten weeks until the championship? Hopefully those lads are coming back fit."
He stressed, however, that Kenny remained optimistic about their prospects.
"That's what he emphasised after Sunday. It was all about building," Smyth explained.
"And now we switch our focus to the summer. We can't be thinking about what happened the last few weeks."
