Richard Dunne took part in Ireland's training session on Tuesday morning ahead of the Euro 2012 Group C encounter with Spain on Thursday.
Dunne, 32, sat out training on Monday due to foot blisters following Ireland's defeat in their opening match against Croatia on Sunday.
Darron Gibson, who had a scan on a thigh problem on Monday, also took part in the session at the Gdynia Municipal Stadium.
Giovanni Trapattoni's side are bottom of Group C following their loss and have world champions Spain to play on Thursday.
A defeat would see Ireland eliminated after only two matches. Italy and Spain drew in the other Group C clash on Sunday.
