Kevin McManamon is in the dark about the extent of the knee injury that has placed a major question mark over Michael Darragh Macauley's championship involvement with the Dubs this summer.
Asked if a lengthy Macauley absence would constitute a big blow, his Sky Blue colleague today admitted: "He would be. I don't know a huge amount about it. People seem to know more than I do, because I haven't spoken to Mick myself.
"Speculation is your word but I don't know a huge amount about it."
Dublin resume collective training this week ahead of their Leinster SFC quarter-final against Wexford or Carlow on June 3. McManamon clarified that Dublin "haven't got back fully yet", hence he hasn't seen the 2013 Footballer of the Year.
Jim Gavin's squad took a five-week break after their Allianz League final loss to Kerry, facilitating the playing of two rounds of the Dublin senior club football championship.
"I loved it, I have to say," the St Jude's man revealed, speaking at a Topaz Cash for Clubs launch event in Clanna Gael Fontenoy GAA club, Ringsend today.
"I was able to get away from the Dublin set-up for a bit and get back, stuck in, with the club. We'd a couple of good wins in the club championship, so it was just nice to get an extended break.
"Usually you don't get away from it for long enough, so we were kind of itching to go back moving properly this week with Dublin. Good to be back."
Páraic Duffy said it was "really important that referees get it right more often this summer", while former top referee Pat McEnaney dispensed with diplomacy, stating that "it was a bit embarrassing at times during last year's championship".
