WWE had been hyping up a big Bray Wyatt vs Brock Lesnar match and then when the show went down it didn’t happen. The match was instead changed to a handicap match where Bray teamed with Luke Harper to take on Lesnar, but Bray never tagged in.
The reason why Bray never tagged in according to the Wrestling Observer Newsletter is because Bray is dealing with a pretty significant back injury. There’s no word on how long he’ll be out of action for.
