With his contract rumored to be expired after "Wrestlemania 31," could current WWE World Heavyweight Champion Brock Lesnar leave the world of sports entertainment to attempt a return Ultimate Fighting Championship (UFC) and the sport of mixed martial arts?
Topps recently released their Ultimate Fighting Championship flagship "Knockout" 2014 card set featuring a "Triple Threads" series, a 'Fist-ogram' series, their "Three of a Kind Triple Autographs” series, and the "Relic" cards series -- which contain fighter-worn shorts, shirts and mats from some of the company's classic fights.
