The Gaeltacht star has not figured since September’s All-Ireland final but has played for his club over the past two weeks, and with Seamus Scanlon on the injured list, Ó Sé could be back in his familiar midfield berth.
Scanlon tore ankle ligaments playing with his club over the weekend and is likely to miss the rest of the league campaign.
Killian Young and Declan O’Sullivan, both out injured for the Dublin game, are also back in the frame with Renard’s Young coming through a weekend club game unscathed.
But Tadhg Kennelly, out for the past three weeks with a calf-strain, remains a doubtful starter.
For their vital home tie with Armagh at Páirc Uí Chaoimh on Sunday, Cork must plan without long-term injury victims Michael Cussen and Kevin O’Sullivan, while Paul O’Flynn of Ballyclough is doubtful because of hamstring trouble.
However, Ballincollig duo John Miskella and Paddy Kelly, plus Nemo’s Derek Kavanagh, are available.
Shane Briggs and Sean Fleming have been recalled to the Waterford team for Sunday’s crucial Allianz NFL game against Sligo at Markievicz Park. Briggs takes over the right corner-back position from Mark Prendergast, while Fleming replaces Michael O’Gorman at full-forward. Waterford must win this one to keep their promotion hopes alive.
Clare are unlikely to finalise their team to play Leitrim at Carrick-on-Shannon on Sunday until after the completion of the County U-21 hurling championship semi-finals on Friday night.
For their away game with Offaly at Tullamore on Sunday, Limerick expect Andrew Lane back in action. The teak-tough wing back damaged a hamstring in the opening game of the competition against Roscommon and has been sidelined since.
Stephen O’Neill is on course to return to the Tyrone colours in time for the All-Ireland champions' Ulster opener against old rivals Armagh at the end of May.
The former footballer of the year has not played for Mickey Harte's side since his star turn against Dublin in the opening round of the National League at Croke Park because of a knee injury.
“He’s coming on well,” said Harte. “He’s recovering well. He’s back training with us now, not with full intensity but as the weeks go on that will improve. He won’t be ready for the Mayo game (on Sunday week) but he should be ready for the championship.”
There was also favourable news for Harte in the shape of goalkeeper Pascal McConnell and talisman Brian Dooher who have made tentative first steps on the road back to recovery after their own recent injuries.
Galway boss Liam Sammon and his selectors have received a double boost ahead of Sunday’s key league clash against Kerry.
Wing-back Darren Mullahy, who missed their only defeat of the campaign to Mayo because of work commitments, is again available.
And so too is attacker Cormac Bane who has recovered from injury and is available for Sunday’s tie where Galway need a point to be guaranteed a place in the final against Kerry.
Former Meath goalkeeper Brendan Murphy, who quit the Royals earlier this year to return to soccer, has now left League of Ireland First Division side Longford Town.
Dublin’s U-21 footballers have two injury concerns ahead of their All-Ireland U21FC semi-final against Cork in Semple Stadium, Thurles (3.30) on Saturday week.
Half-backs Johnny Cooper and Chris Guckian are both current injury concerns.
