How about tickets to a game for his favorite team? You could also get him a personalized football jersey with his favorite player's name or his own name on it. Another idea could be a sports-themed gift basket filled with snacks, drinks, and merchandise from his favorite team. And if he's an avid collector, you could consider gifting him with rare or vintage memorabilia from the sport or his favorite team.
Or you can get him a star map with the date of your anniversary.
