#4. Former WWE Superstar Buddy Murphy
Buddy Murphy and Rey Mysterio were part of a storyline on WWE TV back in 2020 which surrounded Mysterio's daughter Aalyah. The story was seemingly dropped when Seth Rollins headed off on paternity leave at the end of the year.
Murphy has since been seen trying to win back the trust of Seth Rollins but was unable to do so when he couldn't defeat Cesaro. This attack could have been Murphy's attempt to continue to prove himself to Rollins since he hasn't had much luck in WWE in the months following his spat with The Messiah.
If Murphy was the man behind the attack then the reason the storyline was seemingly dropped would make sense. The former NXT Tag Team Champion was released by WWE earlier this week along with Ruby Riott, Aleister Black, Braun Strowman, Lana, and Santana Garrett.
Aleister Black was in the middle of a storyline with Big E when his release was revealed, so being part of a storyline with Rey Mysterio and Seth Rollins perhaps wasn't enough to save Murphy's career.
