Injuries have been one of the most cruel parts of pro wrestling, and Penta became a victim of it this week on Monday Night RAW. The masked luchador was involved in a high-stakes match with Solo Sikoa in what was the quarterfinals of The Last Time is Now Tournament. But El Miedo sustained a potential injury mid-match after landing awkwardly on his left shoulder.The match ended via doctor stoppage around 7-8 minutes early, advancing Sikoa by default. Although WWE hasn't provided an official update on this, there is a high chance that Penta will remain away from action for a while. He is expected to undergo a thorough medical assessment. The 40-year-old's untimely injury may derail several storylines and plans that are in motion.Let's take a look at three plans that may have been ruined due to Penta's injury on RAW.#3. Penta vs. Gunther in the semi-finals of the tournamentThe Last Time is Now Tournament could have gotten a dream match between Penta and Gunther in the semifinals of this contest. Both superstars were seemingly set to clash against each other for the first time. That match was being heavily pushed as a dream high-impact striker vs. luchador clash that would have torn the house down.The Ring General advanced to the semifinals, and fans were hoping to see the masked luchador advance as well. However, El Meido's unfortunate injury shed cold water on those potential plans. The initial plans may have been ruined in light of what transpired on the go-home edition of RAW before Survivor Series: WarGames.#2. The high-profile reunion of Lucha BrosOne of the major plans that may have been ruined due to Penta's injury was the reunion of The Lucha Bros. El Meido was involved in a major program in Lucha Libre AAA Worldwide. He was set to team up with his real-life brother Rey Fenix and battle Dominik Mysterio and El Grande Americano in a massive tag team match.This was huge for AAA, drawing WWE star power to boost attendance and streaming numbers on their platform. For Penta, it was a chance to headline in Mexico post-WWE debut, reinforcing his global draw. However, those plans are now up in the air after what happened on RAW. Penta's absence kills the brotherly reunion dynamic that was the emotional core.#1. AAA Mega Title feud with Dominik MysterioThe AAA program was building Penta as the ultimate foil to Dominik Mysterio's arrogant heel reign. It was expected to lead to a major singles feud between the two stars for the AAA Mega Championship. With both El Meido and Dirty Dom having history, this feud was expected to be a major attraction in Lucha Libre AAA Worldwide.WWE might even be planning for Penta to dethrone Mysterio and give him a major push. However, his injury came like a bolt from the blue, and it may now force the two companies to pivot from that potential AAA Mega Championship feud. The masked luchador is expected to be sidelined for a while, depending on the severity of the injury.
