Republic of Ireland goalkeeper Shay Given missed training on Tuesday morning as he underwent treatment for a stiff neck.
However, the Aston Villa stopper is not considered a doubt for Friday night's Euro 2012 play-off first leg in Estonia. But David Forde has returned to Millwall for treatment on a thigh injury, and Motherwell's Darren Randolph has been added to the squad.
Manager Giovanni Trapattoni was taking no chances with a further three men - Richard Dunne, Keith Andrews and Keith Fahey - also sitting out the session at Malahide.
Dunne and Fahey were both having treatment for minor injuries, while Andrews was simply rested.
