Dominik Mysterio Reportedly Dealing With Shoulder Injury After AAA Guerra de Titanes Event

Concerns are swirling around Dominik Mysterio following his appearance at AAA’s Guerra de Titanes event. According to Bryan Alvarez, the reigning AAA Mega Champion and WWE Intercontinental Champion may have suffered a shoulder injury during the show’s main event.

Dominik teamed with El Grande Americano to take on his father, WWE Hall of Famer Rey Mysterio, alongside Rey Fenix. The babyface duo ultimately scored the victory after interference from Penta, but the spotlight quickly shifted to Dominik’s condition late in the match.

Alvarez noted that the injury appeared to occur after Dominik took a DDT from Rey Mysterio near the closing moments of the bout. Following the move, Dominik was reportedly struggling badly, with limited use of his arm once the match concluded. Based on the way he landed, a shoulder separation is being speculated, though nothing has been confirmed.

Alvarez added that the situation could range anywhere from a minor issue to something far more serious, potentially even requiring surgery. However, the full extent of the injury won’t be known until Dominik undergoes a medical evaluation.

After the bell, Dominik was seen shoving his own partner, El Grande Americano, before walking to the back under his own power. Americano appeared confused by the exchange and later shook hands with Rey Mysterio before exiting the ring.

At this point, there is no official word on how much time, if any, Dominik may miss. With him currently holding both the AAA Mega Championship and WWE Intercontinental Championship, a lengthy absence would create major ripple effects across two promotions.

Dominik most recently reclaimed the Intercontinental Title at Survivor Series: WarGames 2025, defeating John Cena with assistance from Liv Morgan, continuing his controversial run at the top of WWE’s mid-card.

AAA closed out the year in style with Guerra de Titanes, a wild event packed with lucha chaos, celebrity moments, shocking alliances, and future-shaping outcomes. Corey Graves, JBL, and Konnan guided fans through the English commentary as the action unfolded.

La Parka & Octagón Jr. defeated Mr. Iguana & Niño Hamburguesa, Cruz Del Toro & Joaquin Wilde, Bravo Americano & Rayo Americano

The show kicked off at full throttle with a four-team tag match featuring La Parka & Octagón Jr., Mr. Iguana & Niño Hamburguesa, Cruz Del Toro & Joaquin Wilde, and Bravo Americano & Rayo Americano. From the opening bell, the bout was a nonstop sprint filled with dives, creative offense, and crowd-pleasing madness.

Standout moments included Iguana’s spinning headscissors, Wilde’s slingshot dive to the floor, Parka walking the ropes before launching himself outside, and Hamburguesa using his signature hamburger distraction to help Iguana score a big rana. The closing stretch saw Parka and Octagón hit a stereo Spanish Fly on Cruz Del Toro, followed by Octagón wiping everyone out with a tornillo. Parka sealed the win with a playful dance and slam, putting his team firmly in line for a future title opportunity.

After the match, Parka shared a wholesome moment dancing with a young fan—only for another masked Parka at ringside to reveal himself as boxing superstar Canelo Álvarez, drawing a huge reaction.

AAA Latin American Championship: El Hijo de Dr. Wagner Jr. (c) defeated Ethan Page to retain the Title

El Hijo de Dr. Wagner Jr. successfully defended the AAA Latin American Championship against Ethan Page, though not without drama. Page immediately leaned into his dirty tactics, even twisting Wagner’s mask to blind him and scoring a near-fall with a powerbomb.

Page appeared to steal the title after using a wrench behind the referee’s back, but Mr. Iguana rushed in to expose the cheating. Once the referee discovered the weapon, the decision was overturned and the match restarted. Wagner wasted no time, planting Page with the Wagner Driver to retain his championship decisively.

Carnival of Carnage: Psycho Circus & Pagano defeated The Wyatt Sicks

The “Carnival of Carnage” match between Psycho Circus & Pagano and The Wyatt Sicks was exactly as unhinged as advertised. The action began backstage in a twisted carnival setup, complete with surprise appearances from Mascarita Sagrada swinging a kendo stick and Pimpinela Escarlata distracting Joe Gacy with a kiss.

After Pagano was powerbombed through a table, the fight eventually spilled back to the ring with the Wyatts holding a numbers advantage. That changed when Pagano returned to even the odds. Psycho Clown fully embraced the madness, ripping off his own mask before chaos erupted around the ring. In the end, Psycho Clown drove Dexter Lumis through a table with the Psycho Driver to score the win.

AAA World Cruiserweight Championship: Laredo Kid (c) defeated Je’Von Evans and Jack Cartwheel to retain the title

Laredo Kid retained the AAA World Cruiserweight Championship in a jaw-dropping three-way match against Je’Von Evans and Jack Cartwheel. The bout felt like a highlight reel from start to finish, featuring aerial insanity, destroyers, massive dives, and lightning-fast counters.

The finish came when Laredo unveiled a never-before-seen Spanish Fly variation, dropping Cartwheel in spectacular fashion to keep his title in one of the night’s most memorable performances.

Natalya, Lola Vice & Faby Apache defeated Las Toxicas

Faby Apache teamed with Natalya and Lola Vice to defeat Flammer, La Hiedra, and Maravilla. The heels isolated Lola early, but a hot tag to Natalya shifted the momentum. The babyfaces landed a double Hart Attack before the match broke down into chaos. Faby ultimately pinned the women’s champion with a crisp bridging snap dragon suplex.

Hijo del Vikingo defeated Dragon Lee with help from Omos

Hijo del Vikingo defeated Dragon Lee in a heated battle that took a shocking turn. Dragon nearly had the match won after landing his finisher, but a downed referee changed everything. Vikingo resorted to a low blow, and then the real surprise arrived—Omos.

Dragon attacked the giant, only to be flattened by a massive powerbomb. Vikingo capitalized with a 450 splash to score the victory as Omos returned the referee to the ring. Afterward, Dorian Roldán appeared and announced the formation of El Ojo, officially aligning Vikingo and Omos as a new power faction in AAA.

Rey Mysterio & Rey Fenix defeated Dominik Mysterio & El Grande Americano

In the main event, Rey Mysterio and Rey Fénix defeated Dominik Mysterio and El Grande Americano in an emotionally charged tag match. The crowd loudly booed Dominik as he targeted his own father, even tearing at Rey’s mask during the closing moments.

Outside interference teased the finish, but Rey finally connected with the 619 and followed with a slingshot splash to pin his son, sending the fans home happy. After the match, Dominik stormed off alone with his titles, while Americano refused a babyface moment, leaving Rey, Fénix, and Penta confused but celebrating with the crowd.
