Andrea Pirlo sat out of Italy's Euro 2012 training session on Wednesday with a 'minor knock'.
The Juventus midfielder had a brief discussion with members of the team's coaching staff before returning to the dressing room in Krakow.
However, the 33-year-old is expected to be fit for Sunday's Group D opener with holders Spain.
The Azzurri have also been drawn against Croatia and the Republic of Ireland for the tournament.
