In May 2005, aged 34, he came out of retirement and travelled to Bolton, England for a third fight with Amir Khan. He had beaten Khan twice already the previous year – in the Pre-Olympic tournament and the Olympic Lightweight final – however Khan had become a popular attraction in the UK and a third fight was arranged to set up his professional debut. Khan beat Kindelan on points 19-13.
Having retired, he is generally considered as one of the greatest amateur boxers ever seen, leading to the comment during his final fight by the boxing commentator that he was "a professional in a vest".
Typical for athletes from Cuba, where professional sport is prohibited, his reward is his pride in representing his people on the Olympic stage. He said, of being offered $1 million to compete professionally, "I thanked them, but money cannot buy what I have."
