The reason why Bray Wyatt has not been wrestling on WWE television is that he is suffering from a back injury, an injury which is considered bad enough that he is not allowed to get physical.
Wyatt was advertised to be taking on Brock Lesnar at the Roadblock WWE Network event last week however before the match started Wyatt said that the match is now a 2 on 1 handicap match, with Luke Harper tagging along.
Harper ended up wrestling the whole match, taking seven German suplexes, as Bray stayed on the outside and never tagging in.
The Wyatts have no opponents for WrestleMania despite being one of the most popular and dominating factions in the company. The remaining members of the Wyatt Family are expected to be part of the Andre The Giant Memorial Battle Royal.
