Spain striker Raul was named in the Real Madrid squad for Saturday's league match against Alaves, three months after suffering a serious knee injury.
Their captain's return is a major boost for Real ahead of next week's Champions League knockout tie against Arsenal and means he is on course to lead Spain at the World Cup in Germany.
Raul suffered a partial tear of the cruciate ligament and damaged the cartilage in his left knee when he miscued a shot during Real Madrid's 3-0 defeat by Barcelona on November 19.
Club doctors opted to follow a "conservative" programme of treatment to deal with the injury rather than surgery in the hope that the player would make a more rapid recovery.
