Collectors have seen the Donruss logo on a lot of different products over the years. Later this month though, they'll see it in places it's never been before: on the shirt and fight shorts of a UFC champion.

Welterweight champ Matt Serra will sport the Donruss sponsorship on April 19 for his rematch with Georges St. Pierre at UFC 83. It's the first time the company has done an individual sponsorship and a natural way to promote the mixed martial arts cards that will appear in its upcoming sequel to Donruss Americana.

The Ring Kings series will feature regular, autographed and memorabilia cards and are set to appear in Donruss Americana II. Along with Serra and St. Pierre, other big MMA names on the checklist include Randy Couture, Rich Franklin, Forrest Griffin and Dan Henderson.

Visit Donruss' site to find out more about Ring Kings, and look for Americana II in July.
