It looks like Samoa Joe may be injured or, at the very least, he's banged up. Joe was at the NXT live event in Riverside, CA but he did not wrestle. He did address the fans and, while trying to stay in character, told the fans that he was not cleared to wrestle. Joe was supposed to team up with Bobby Roode in the main event against Shinsuke Nakamura and Tye Dillinger. However, Andrade "Cien" Almas teamed with Roode while Joe watched from ringside. Joe attacked Nakamura a couple of times during the match before being ejected by the referee.
It was noticeable during the Joe vs. Nakamura match in Australia that they were working a slower, smarter pace and the match was down several notches from what they did at the last couple of Takeover shows. He did wrestle at the 12/13 show in Sydney, Australia but he was protected in a multi-man match with Roode and Elias Samson as his partners against Nakamura, Murphy and Dillinger. The original plan was for a Fatal 4 Way match with Joe vs. Nakamura vs. Roode vs. Dillinger but plans changed, presumably to protect Joe and to limit how many spots he does.
He is still be advertised to appear at the show in Las Vegas on Saturday night. If we hear further word on Joe then we'll pass it along. Hopefully, they have plans to move him up to the main roster because it's long overdue for him and Nakamura.
