All good things must come to an end. In this case, the good thing is the Strikeforce promotion that has essentially served as a UFC feeder league, as well as a home for those high profile fighters on the Zuffa poo-poo list, since its inception. The California-based, Zuffa-owned promotion will lock its cage doors one last time Saturday night as “The Great” Nate Marquardt (32-10-2) defends his Strikeforce Welterweight Championship for the first and only time against dangerous submission fighter “Sponge” Tarec Saffiedine (13-3). Co-headlining the event is Strikeforce Heavyweight Grand Prix Champion Daniel Cormier (10-0) who will face “The Soldier” Dion Staring (28-7). “The Warmaster” Josh Barnett (31-6) will make his first appearance since losing in the finals of the Grand Prix as he goes toe-to-toe with “The Hun” Nandor Guelmino (11-3-1) in the anchor bout, and “The Dream Catcher” Gegard Mousasi (32-3-2) will face the always dangerous “Mak” Mike Kyle (19-8-1). Opening duties for the main card fall squarely on the shoulders of “Jacare” Ronaldo Souza (16-3) who looks to continue rebuilding his title dreams at the expense of “Short Fuse” Ed Herman (20-8).
