Bray Wyatt worked a dark match at Tuesday's Smackdown tapings after sustaining a sprained ankle prior to WrestleMania this weekend. Live reports stated that Wyatt didn't see much in-ring action during the match, but wasn't showing any indications of injury.
According to PWInsider, the Wyatt injury was so bad Sunday that Wyatt was unable to put weight on the ankle for quite some time. He was also in a cast to the remainder of the day up until his match with Undertaker. Wyatt was carried off on a cart the morning ofWrestleMania 31 after sustaining the injury.
Wyatt wasn't on this week's episode of Raw, so plans moving forward with Wyatt are unknown. Wyatt's WrestleMania opponent Undertaker was also not on the show.
