Details are sparse as of right now, but we can confirm that Samoa Joe has sustained an injury. Earlier this week it was announced that Bayley would be teaming with Samoa Joe for the Mixed Match Tournament, but Kurt Angle announced via Twitter recently that due to Samoa Joe’s injury, he will not compete. Elias will fill the spot for Joe in the tournament.
