The Champions mostly retained their Championships at the latest instalment of WWE Backlash, except for the holders of one specific title.

THE 2021 EDITION WAS TITLED “WRESTLEMANIA BACKLASH”
In 2021, the show was scheduled for the May PPV slot, returning it to its original position of being the post-WrestleMania PPV—as a result, the 2021 edition was titled “WrestleMania Backlash”. There was no paying audience as in WrestleMania 37, and it was first WWE pay-per-view produced from the ThunderDome at the Yuengling Center.
ONLY ONE CHAMPIONSHIP CHANGED HANDS
In the Backlash pre-show, the WWE United States Champion Sheamus threw an open challenge, which would not have his Championship on the line. Ricochet accepted the challenge and in the end, an escape from Brogue Kick and a roll-up attempt was insufficient as “The Celtic Warrior” defeated him after a rising knee.
.@KingRicochet couldn’t overcome United States Champion @WWESheamus in a non-title bout on the #WMBacklash Kickoff, but left with the last laugh.

Next, The Miz, accompanied to the ring by John Morrison, was defeated by Damian Priest in a lumberjack match. The lumberjacks, however, were supposed zombies as a tie-up to “Army Of The Dead”. After that, Bianca Belair defended the SmackDown Women’s Championship against Bayley. Belair won the match after using her braided hair to gain leverage during a pinfall, which Bayley protested following the match.
Yep, we’ve officially seen it all in @WWE. #WMBacklash
