Liv Morgan might be out of action for the foreseeable future ... as the WWE Superstar seemingly injured her shoulder just moments after her match got underway on "Monday Night Raw."
It all went down after Morgan took on Kairi Sane in a one-on-one showdown in Green Bay. During their scrap, Sane grabbed hold of Liv's leg to execute a takedown ... and when she hit the mat -- Liv immediately reached for her shoulder and rolled out of the ring.
When the broadcast slowed the replay, you could see her right shoulder appeared to pop out of place.
