Brock Lesnar will be at Raw to respond to (accept) Jinder Mahal's challenge for a match at Survivor Series. The word going around at Raw is that John Cena will be the guest referee for the match.
The Raw women are set to take on the Smackdown women at Survivor Series, with Bayley wrestling Sasha Banks to see who will captain Raw's team.
