Sheamus vs. Daniel Bryan was the original plan for this year’s WWE WrestleMania 31 pay-per-view but it was changed to Bryan vs. Dolph Ziggler some time in the last few weeks.
WWE officials are indeed going forward with Bryan vs. Ziggler and we should see that match develop on RAW this week. The change was made because Bryan went to WWE officials and requested a match against Ziggler for WrestleMania 31.
