It is not new that Santana and Ortiz, also known collectively as LAX, are on their way out from Impact Wrestling and will be free agents. Their contracts are set to expire sometime in August, and they have already dropped their Tag Team Titles to The North.
The Wrestling Observer Newsletter is reporting that LAX has already received "significant offers" from both the WWE and AEW. It is being said that there are people within both companies expecting the arrival of the tag team.
As for now, this can all just be taken as speculation, since they are still contractually obligated to Impact Wrestling and no actual deals or agreements have been reached or confirmed.
