Brazilian grappler Walter Walker says he is moving away from his signature heel-hook game and wants to showcase his striking. Walker is scheduled to face Thomas Petersen on July 25 in Abu Dhabi.
Brazilian submission specialist Walter Walker is set to face American fighter Thomas Petersen on July 25 in Abu Dhabi, with Walker declaring a shift away from the heel-hook tactics that defined his career to this point.
Walker made waves alongside the fight announcement by stating he intends to leave his signature leg-lock game behind and instead put his striking on display. The declaration signals a deliberate reinvention for the Brazilian grappler, who built his reputation around lower-body submission attacks.

Standing across from him will be Thomas Petersen, known as "The Train," a 31-year-old southpaw out of Spartan MMA. The American carries an 11-4 record and presents a well-rounded threat. Petersen lands 3.1 significant strikes per minute at an impressive 59 percent striking accuracy, making him a dangerous opponent for anyone looking to test their standup game. He also averages 3.01 takedowns per 15 minutes, giving him a genuine path to controlling where the fight takes place.
Why it matters
- Walker's stated move away from heel-hooks reshapes the stylistic equation entirely, removing his most dangerous weapon and inviting a striking exchange
- Petersen's 59 percent striking accuracy means Walker's newly declared stand-and-trade approach carries real risk
- Petersen's takedown volume gives him the ability to neutralize Walker on the feet and drag the fight to the mat on his own terms
- The Abu Dhabi setting continues to serve as a high-profile stage for grappling-oriented matchups, adding further weight to the bout
