Walker Rules Out Fighting Brother Valter Ahead of UFC Vegas Main Event
Johnny Walker says he would never accept a fight against his half-brother Valter Walker, and would rather train with him instead.

Johnny Walker has ruled out ever fighting his half-brother Valter Walker, drawing a clear family line ahead of his UFC Vegas 124 main event against Waldo Cortes-Acosta. Speaking to MMA Fighting, the Brazilian light-heavyweight-turned-heavyweight said he would not accept a matchup against his half-brother, even as both men climb the heavyweight rankings. Instead, Walker said he would consider training with Valter, framing their relationship as a partnership rather than a rivalry. The comments underline how seriously Walker takes the family bond, at a time when the UFC heavyweight division is short of fresh contenders and intriguing matchups are always in demand. For now, his focus is firmly on Saturday's main event in Las Vegas, where Cortes-Acosta stands between him and a statement win. The bout was elevated to headline status after Sean Brady's injury scrapped the originally scheduled main event, giving Walker a prime platform. Whatever happens next in the division, one fight is off the table: Walker versus Walker will not happen.
