Fulham defender Stephen Kelly has been ruled out of Ireland's European Championship play-off, second leg against Estonia with a groin injury, but Damien Duff should be fit.
Duff had been considered a doubt after he was winded in the 4-0 first leg win but is likely to start.
Kevin Doyle will return to the team after missing the first game through suspension, while John O'Shea will come in for Kelly.
Leon Best remains with Newcastle and is unlikely to travel to Dublin.
