On March 15, 2009, Guerrera made a surprise return to AAA at the annual Rey de Reyes event. Juventud helped Charly Manson and D-Generation-Mex win their match and joined D-Generation-Mex. Shortly after his return to the company, Guerrera suffered bruising and a broken nose in a backstage fight with Konnan and Jack Evans. The fight started after Guerrera accused Konnan of defecating in his bag, which Konnan denied (but it was X-Pac who did it as revenge for exposing X-Pac suicide attempt), and then Evans, with whom Guerrera had had a match that evening, allegedly grabbed Guerrera from behind, provoking the fight.
