Judging from the utter lack of promotion they’ve done for Cerrone vs. Henderson, it seems like the WEC is already treating this show as a tax write-off. And that’s unfortunate, because Sunday’s event has more than its share of potential barn-burners. Donald "Cowboy" Cerrone and Benson Henderson meet in the main event to determine the league’s interim lightweight champion, while top featherweights Rafael Assuncao and Wagnney Fabiano and undefeated lightweight Dave Jansen will also be in action. The above promo clip introduces us to Yves Jabouin, a 14-4 striker who trains with Georges St. Pierre at Tri Star gym in Montreal; he’ll be facing Assuncao on WEC 43′s main card. According to GSP, Jabouin is incredibly fast, and will bring things that MMA fans have never seen before. After the jump, Ben Henderson takes us around his gym and gets savagely armbarred by a four-year-old.
