St. Preux (11-5) rocketed up the Strikeforce light heavyweight ranks, winning his first five consecutive bouts for the promotion. His last time in the cage, however, he ran into former champion Gegard Mousasi, suffering the first defeat of his tenure in the promotion.
He’ll make his first start in eight months in August when he squares up with Cook, who is stepping into the Strikeforce cage for the third time.
Cook (12-4) is also coming off of a loss, that being to Trevor Smith last November. That loss ended a five-fight winning streak for Cook.
