Just two weeks ago, Valter Walker's chance to fight at home as part of UFC Rio was dashed when Mohammed Usman pulled out of their fight two days prior to the event. As luck would have it, the UFC was able to get him on UFC 321, pairing him up with English heavyweight newcomer Louie Sutherland. Valker came into the fight with an unheard of three straight heel hook submission wins, while Sutherland had won four straight, all for Levels Fight League.
