Dominik Mysterio Retains AAA Mega Championship, Sustains Head Injury at Rey de Reyes

Dominik Mysterio successfully retained the AAA Mega Championship against El Hijo del Vikingo in a No Disqualification match at AAA Rey de Reyes on Saturday, March 14, in Puebla, Mexico. The highly anticipated bout saw Mysterio sustain a head injury during the contest. This championship defense followed a contract signing with new stipulations and unfolded amidst significant developments concerning Mysterio's status in WWE, including a recent championship loss and internal conflict within his stable, The Judgment Day.

Pre-Match Build-Up and New Stipulations

The path to the AAA Rey de Reyes championship defense was set during a weekly episode of AAA, featuring a pivotal contract signing. During this event, El Hijo del Vikingo introduced two critical new stipulations for the upcoming match.

The first stipulation declared that should Vikingo emerge victorious, Mysterio would be compelled to depart Mexico and permanently exit AAA. The second confirmed that the championship match would be contested under No Disqualification rules.

A tense confrontation ensued after the signing, involving El Hijo del Vikingo, accompanied by Dorian Roldan and Omos, and Dominik Mysterio. The situation escalated when El Grande Americano intervened, attempting to strike Omos with a chair. This action created a diversion, allowing Mysterio to exit the scene. Further complicating matters, an individual identified as The Original El Grande Americano later appeared and attacked the first Americano.

The AAA Rey de Reyes Main Event

The much-anticipated AAA Mega Championship match, headlining AAA Rey de Reyes, unfolded on Saturday, March 14, in Puebla, Mexico. Contested under No Disqualification rules, the bout saw both competitors utilize an array of objects, including kendo sticks, steel chairs, and trash cans.

A pivotal moment occurred during the intense contest when Vikingo struck Mysterio with a steel chair, resulting in a visible gash on Mysterio's head. Adding to the chaotic environment, Dorian Roldan and Omos were present at ringside, actively assisting Vikingo throughout the match.

Despite the injury and outside interference, Mysterio ultimately secured the victory by pinning Vikingo after executing a decisive Frog Splash, thereby retaining the AAA Mega Championship.

Post-match, Mysterio confirmed his championship retention on social media, sharing an image that visibly displayed his head injury.

Post-Match Landscape and WWE Crossroads

Dominik Mysterio's successful title defense ensures his continued reign as AAA Mega Champion and his presence on the AAA roster. Looking ahead, El Grande Americano, the winner of the 2026 AAA Rey de Reyes tournament, is now slated to challenge Mysterio for the championship at a future event.

These significant AAA developments occur concurrently with pivotal changes in Mysterio's WWE career. He recently lost the WWE Intercontinental Championship to Penta on the March 2 episode of Monday Night Raw. This championship change was notably influenced by his stablemate from The Judgment Day, Finn Balor, who intervened to prevent Mysterio from using a weapon.

The internal friction within The Judgment Day escalated the following week on WWE Raw. Mysterio confronted Balor, leading to a physical altercation that involved JD McDonagh, Liv Morgan, and Raquel Rodriguez. Speculation is now mounting regarding a potential high-profile match between Balor and Mysterio at WrestleMania 42 in Las Vegas, although no official announcement has been made by WWE.
