However, one bout may have turned into a nightmare for a major superstar and his fans, as there have been chatters about him sustaining an injury.The star in question is Penta, who competed against Solo Sikoa in the "Last Time is Now" tournament to qualify for the finals and get one step closer to becoming the final opponent of John Cena.During the match, Penta ran onto the barricade and connected with a headscissors, but unfortunately, he landed awkwardly on his left shoulder. Even Wade Barrett from commentary expressed concern about an injury. The medical officials rushed in, took him out, and the bout ended with a referee stoppage. Solo Sikoa was declared the winner as the former AEW star wasn't able to compete.In a shocking twist, the 40-year-old might go on hiatus if his injury turns out to be serious and he requires additional medical care. If that is the case, the red brand will lose another attraction from its roster.That said, the angle proposed above is speculative, and nothing has been officially confirmed.A major match for the WWE RAW star may get canceledAt AAA Alianzas, Dominik Mysterio and El Grande Americano locked horns with Dragon Lee and El Hijo del Vikingo.
