An experienced AEW star has seemingly returned to the promotion after nearly a year following rumors of backstage heat. This sudden re-emergence occurred during the latest episode of Collision.According to Fightful Select, Serena Deeb was spotted backstage at AEW Collision and is said to have been present in more than just a visiting capacity. The former WWE star has not been seen even behind the scenes in the promotion for the entire year.The reason for her absence is allegedly due to a significant backstage disagreement with AEW higher-ups. Additionally, Deeb has stated that she suffered an injury which is why she has not been in the promotion as of late.Her most recent appearance was on an episode of Dark: Elevation against Haley J in October of last year. Since then, she has not competed, had any influence creatively, or attended to her duties as a coach in the promotion.While she was an active member of the promotion, The Professor put on a handful of outstanding matches. Her bouts with Hikaru Shida and Toni Storm were notable standouts.Her recent appearance in the promotion could be a sign of better things to come for the tenured veteran. Although, only time will be the best judge of this.
