How about a special edition boxing glove signed by one of his favorite boxers or framed photo of his favorite boxing match? You can also consider a boxing robe with his name or initials embroidered on it, a boxing-themed mug, or a boxing gym membership for a few months. Another idea is a subscription to a boxing magazine or book on the history of boxing.
Or you can get him a star map with the date when he welcomed you in this world.
