The Spain goalkeeper has been missing since fracturing his left hand in January against Valencia in the Copa del Rey.
Casillas has been working out himself, but is expected to rejoin the Real squad over the next few weeks once the club's medical staff give him the go-ahead.
Former Villarreal and Sevilla goalkeeper Diego Lopez has been deputising for Casillas since his injury, helping his side progress to the Spanish Cup final and the last eight of the Champions League.
