Last night, O'Dwyer named three changes in attack from the side that started against Derry for tomorrow's Bank of Ireland All-Ireland SFC quarter-final with Armagh at Croke Park.
Barry Brennan, Stephen Kelly and Brian 'Beano' McDonald return, with Kevin Fitzpatrick, Shane Cooke and Chris Conway starting on the bench.
During the roller-coaster duel with Derry, the Laois manager replaced four of his forwards, including the entire full-forward line of Donal Brennan, Cooke and Conway, and centre-forward Fitzpatrick. Barry Brennan now takes over the centre-forward position from Fitzpatrick. Stephen Kelly replaces Cooke at full-forward, while McDonald is preferred to Conway at left corner-forward. These changes do not come as a major surprise, because, until O'Dwyer began a radical overhaul of his attack in the second half of the Derry game, things looked dire in the extreme for his charges.
Armagh make one change from the side that beat Tyrone in controversial circumstances in the Ulster final replay.
Martin O'Rourke takes over the right half-forward position from his brother Aidan. Wing-back Ciaran McKeever and midfield player Paul McGrane, who were both suspended for a month following the tempestuous replay with Tyrone, but on appeal had their suspensions lifted, will occupy their customary positions.
Galway have made just one positional change for Sunday's All-Ireland SHC semi-final against Kilkenny from the team which defeated Tipperary.
Tony Óg Regan, who moved to full-back in that game, starts at number three as expected, with Shane Kavanagh moving out to centre-back.
Top scorer Ger Farragher has been passed fit and will start in the right corner, while Conor Hayes and his selectors are further boosted by the availability of full-forward Niall Healy. Both had been doubtful after picking up 'dead legs' in a training match last week but have made a good recoveries this week and trained last night.
Galway have decided not to start Kevin Broderick, but the former All-Star will be included among the subs having being out for ten weeks after surgery on a leg injury.
