O’Connor out of clash with Blues
Cillian O'Connor will not play any part in Saturday's crunch league tie between Dublin and Mayo in Croke Park as he continues his recover from knee surgery.
Mayo are also without Tom Parsons, Cian Hanley (both knee injuries), last year's U21 captain Ryan O'Donoghue (ankle) and Evan Regan (shoulder) although Seamus O'Shea played in a recent challenge match and could be part of James Horan's match-day panel.
Horan must also decide whether to pick 2016 and '17 All Star David Clarke in goals or Breaffy's Robbie Hennelly.
Hennelly was preferred for both of Mayo's FBD League games and their first two Division matches against Roscommon and Tyrone.
Clarke started against Cavan in their most recent match two weeks ago.
Hennelly's last appearance in Croke Park was the 2016 All-Ireland SFC final replay, when he was black-carded after fouling Paddy Andrews for a penalty which Diarmuid Connolly converted.
Meanwhile, Ciarán Kilkenny could be in line to make his first Dublin appearance of the year this Saturday in Croke Park.
Kilkenny has not been part of any match-day panel for Dublin's opening games in the competition having returned from an extended holiday in Australia at the end of January.
He lined out for his club Castlenock against Cuala in a challenge match two weeks ago and started their 5-12 to 2-6 victory over Naomh Mearnóg in the opening game of AFL Division 2.
Kilkenny, Philly McMahon, Cian O'Sullivan and Stephen Cluxton are the four members of last year's All-Ireland winning starting 15 yet to play in the League.
