Gift idea for my boyfriends 21st birthday?

Hey guys, so my boyfriends birthday is in about a week and i am having a really hard time coming up with a gift, we've been dating for a year and a half and I'm still only 19 so I can't really buy him any alcohol. I am on a budget and I only have about 40-50 bucks. He loves the broncos, and loves pretty much all things football and wrestling, he plays xbox but not very often. He's such a good person and is always helping out other people, i really want to get him something nice, but it's gonna be hard on my budget/:
