@superbeastmma: Fresh off his stoppage win over Waldo Cortes-Acosta, Walker says he’s willing to turn around in just ONE WEEK if Ciryl Gane or Josh Hokit needs a replacement at UFC 334. “If they need someone to step in, I’m here.” Walker is offering his services—the UFC hasn’t announced him as the backup. But with two stoppage wins since moving to heavyweight, he’s making his title ambitions clear. 💥 Would you give Walker the call, or should he beat another contender first? 👇 #UFC334 #JohnnyWalker #UFC #MMA #Fight
