Nia Jax, Bray Wyatt, and Bo Dallas are all in Baltimore for Raw. That doesn't necessarily mean they are going to be on the show, because the Raw crew all had to be there to fly to Glasgow, Scotland for the Wednesday house show. Wyatt has been cleared. Dallas had not been cleared as of a few hours ago but was being evaluated today.
Jax was not ill, and had just taken a few weeks off and was always scheduled back starting today for the European tour. As noted earlier today, Roman Reigns is right now expected back for the November 13th Raw show in Atlanta.
Alexa Bliss vs. Mickie James for the Raw Women's Championship and Finn Balor vs. Cesaro are scheduled for the show tonight. If James were to win, theoretically they'd flip-flop her and Bliss' matches at Survivor Series.
The men's Survivor Series match, according to multiple sources, will be Kurt Angle, Braun Strowman, Samoa Joe, Roman Reigns & Finn Balor vs. Shane McMahon, Bobby Roode, Randy Orton, Shinsuke Nakamura & AJ Styles. The current issue of the Observer covers the rest of the card as that was the only match not finalized this past week.
