Zayn has been out injured after a rotator cuff injury suffered several months back. As of this writing, there is no word on if he will be wrestling at the events.
The reason that Zayn will be appearing at these two shows is because of the partnership between WWE and Evolve. As noted, it is expected for the two companies to make an official announcement of their partnership sometime this week.
