While a majority of professional wrestling fans in the United States focus on WWE and AEW, professional wrestling is an international phenomenon, with different regions developing their own iconic styles.

This includes the Consejo Mundial de Lucha Libre (CMLL). Originally founded as Empresa Mexicana de Lucha Libre in 1933, CMLL is the oldest professional wrestling promotion still in existence.

Currently, CMLL has a working relationship with AEW, allowing stars from both companies to work in the other.

Unfortunately, it appears a fan-favorite AEW Superstar was injured in this exchange.

Today, CMLL announced that former AEW TBS Champion Willow Nightingale would be unable to compete in two of their events this weekend, Arena Coliseo Saturday and Arena Mexico Family Sunday, as she suffered a concussion.

“We regret to inform our loyal fans that AEW Superstar Willow Nightingale will be unable to participate in Sabado de Arena Coliseo and Domingo Familiar at Arena Mexico as planned due to a concussion suffered during her participation in the Women’s Grand Prix”, CMLL said in a statement on.

“In accordance with concussion protocols established for CMLL and AEW, Willow must sit out both appointments to ensure her well-being and full recovery.”

Instead, Nightingale was replaced by CMLL World Champion Zeuxis for tonight’s match at Arena Coliseo and CMLL 2024 Women’s Universal Champion Persephone tomorrow at Arena Mexico.

“We thank all our fans for their understanding and we assure you that these two champions will offer the spectacle and quality that characterize our wrestling,” the press release continued. “Come to Arena Coliseo and Arena Mexico to enjoy the best wrestling in the world!”

Nightingale confirmed the news by sharing the original post on her own page.

This comes after Nightingale appeared at CMLL’s Viernes Espectacular event yesterday, where she competed in the 2024 CMLL Women’s International Grand Prix as a member of the World Team.

After debuting on the independent circuit in 2015, Nightingale debuted in AEW and Ring of Honor (ROH) in 2021. She quickly made a name for herself, defeating Julia Hart for the AEW TBS Championship on April 21, 2024.

Unfortunately, his reign would come to a quick end when Mercedes Moné defeated her on May 26, meaning she only held the title for 35 days.

Outside of AEW, Nightingale would find championship success in several promotions, including New Japan Pro Wrestling, World Wonder Ring Stardom, and CMLL.
