As noted, Daniel Bryan’s father unexpectedly passed away and Bryan found out as he returned from his honeymoon. WWE officials did give Daniel Bryan the option of skipping Monday’s RAW altogether and to go home but he said no.
The angle with Kane was done to get Bryan off the show early. The impression was given that Bryan would be back for next Monday’s RAW but officials are perfectly fine with him taking off until Extreme Rules if he wants to.
There’s a feeling that the angle with Kane came off so strong that they could keep Bryan out until Extreme Rules and the match would have more of an underdog vs monster feel to it.
