As noted over the weekend, Andrade El Idolo has been teasing that he is leaving AEW. That seems to be more of an angle that an actual departure because Tony Khan has stated that he is not granting releases. Another AEW star is also teasing that he's done.
Shawn Spears posted a "Goodbye" GIF on Twitter and then later deleted it. A short time later, Sammy Guevara tweeted, "You are a jobber. A favor hire. Be grateful b*tch."
Again, there is no confirmation that Spears is leaving aside from the deleted tweet but Guevara's tweet might mean that this is just the start of an angle to build up a match. Spears signed with the company in 2019 but he hasn't been featured much on Dynamite, especially this year. The last time he wrestled was on the 5/25 episode in a match against Wardlow.
If Spears is leaving, then it could simply be that his contract expired and both sides did not reach an agreement for a new deal.
Spears later posted this Adam Sandler laughing GIF:
