#3 Triple H - Chair shot to the head (WWE WrestleMania 27)
In 2010, WWE confirmed in an email to the Hartford Courant that the company’s Talent Wellness Program had been amended, specifically regarding the Impact Concussion Management Program.
The rule change “eliminated the use of folding chairs or props to strike an opponent in the head” – something that had been common in WWE for decades, especially during the Attitude Era.
One year after the rule was introduced, Triple H struck The Undertaker over the head with a steel chair during their 29-minute No Holds Barred match at WrestleMania 27.
Although the match stipulation essentially meant anything was allowed, the steel chair shot to the head resulted in both Superstars receiving real-life fines for the incident.
WWE’s corporate website even published an article confirming that The Undertaker and Triple H had been punished for their use of the steel chair, but the page has since been deleted.
Other than the WrestleMania 27 incident, there has been no indication over the last decade that WWE plans to bring back steel chair shots to the head.
