Rousimar Palhares is a Brazilian mixed martial artist currently competing in the Welterweight division of Absolute Championship Akhmat (ACA). A professional competitor since 2006, he has competed for the Ultimate Fighting Championship (UFC), World Series of Fighting (WSOF), Fight Nights Global (FNG), and Konfrontacja Sztuk Walki (KSW). His nickname Toquinho, Portuguese for "little tree stump", comes from his short, stocky, heavily muscled build and the low success rate his opponents have had in grappling him down to the canvas. Palhares is primarily known for his powerful ground game. Of his 16 submission victories 12 have come from leg locks. He is also known for his refusal to release submission holds when either the opposing fighter has signaled submission or the referee has called a stop to the bout, causing him to be fired by the UFC, and WSOF.

Tomasz Witold Drwal is a Polish professional mixed martial artist and boxer who most recently competed in the Middleweight division of KSW. A professional competitor since 2004, Drwal has also competed for the UFC.
