Background in
Columbus, Ohio.
Extreme Rules was an annual
professional wrestling event produced by
WWE since 2009. The
concept of the event was that it featured various matches that were contested under
hardcore rules and generally featured one
Extreme Rules match. The defunct
Extreme Championship Wrestling promotion, which WWE acquired in 2003, originally used the "extreme rules" term to describe the regulations for all of its matches; WWE adopted the term and had since used it in place of "hardcore match" or "hardcore rules". The previous year's event was titled
The Horror Show at Extreme Rules, due to having
horror-themed matches on its card; the 2021 event would mark a return to its original name. The 2021 event was the 13th Extreme Rules and featured wrestlers from the
Raw and
SmackDown brand divisions. The event aired on
pay-per-view (PPV) worldwide and was available to
livestream on the
WWE Network in international markets, and was the first Extreme Rules to livestream on
Peacock after the American version of the WWE Network merged under Peacock in March. The 2020 Extreme Rules event was originally to take place at the
SAP Center in
San Jose, California, but had to be relocated to the
WWE Performance Center in
Orlando, Florida and held
behind closed doors due to the
COVID-19 pandemic. The SAP Center put out an official statement that they would instead host the 2021 event. The venue also announced that there would be no refunds (unless a new date was not determined within 60 days), but tickets purchased would be honored for the following year's event. However, in May 2021, it was reported that due to the pandemic, the 2021 event would be held on July 18 from the
WWE ThunderDome bio-secure bubble at the
Yuengling Center in
Tampa, Florida, but after WWE announced that they would be resuming live touring in mid-July, that date was instead given to
Money in the Bank. On July 9, 2021, WWE then announced that Extreme Rules would be held on September 26 at the
Nationwide Arena in
Columbus, Ohio, Tickets went on sale on July 16 through

Bálor then got his opportunity at the title on the September 3 episode of
