As I write this, we're only a short time away from finding out who emerges with the victory in an intriguing fight between Randy Couture and Brock Lesnar at UFC 91. Though both UFC stars are certain to be a big part of future trading card releases under Topps' exclusive deal with the company, they already can be found on various types of trading cards.
Former WWE champion Lesnar has appeared in numerous sets of Topps wrestling cards. He also has official NFL rookie cards from several 2004 Donruss Playoff products thanks to his short-lived attempt to make the Minnesota Vikings.
Couture has autographs and memorabilia cards already on the market thanks to sets like Donruss Americana II and its Ring Kings cards - one of which is pictured here. Lesnar isn't on the checklist, but plenty of other top MMA stars are, and you can get a look at many of their signatures in the Ring Kings autograph gallery linked below.
