Italy playmaker Andrea Pirlo was back in training on Thursday after he was rested as a precautionary measure yesterday.
The 33-year-old returned to action in Krakow this morning which will come as a boost to boss Cesare Prandelli ahead of the Spain game.
Cagliari defender Davide Astori was also included after he joined up with the rest of the squad in Poland this week.
Astori has been selected as cover for Andrea Barzagli should the Juventus man be ruled out of the competition with a calf strain. A decision on his inclusion will be made on Friday.
Meanwhile, Hungarian official Viktor Kassai will take charge of the Azzurri’s opening Group C game on Sunday.
Italian referee Nicola Rizzoli has been handed Monday’s tie between France and England.
