Key changes have been made to WWE WrestleMania 33 event, according to the Wrestling Observer.

While the full content of changes are not known, it's being said that The Undertaker will be the only "non-regular" talent to be wrestling on show, although that could certainly change given the fact that past names are seen as an attraction for the biggest show of the year.

The following matches are said to be a lock and will remain unchanged:

- Brock Lesnar vs. Bill Goldberg
- Seth Rollins vs. Triple H
- Big Show vs. Shaquille O’Neal

The WrestleMania card is expected to be finalized internally within two weeks.
