John Morrison is currently in Memphis, the site of tonight’s SmackDown, according to PWInsider, so it’s possible that he could make his WWE return tonight. It’s also of course possible that he is just backstage and isn’t scheduled to appear on TV tonight.
Morrison signed with WWE back in September, but WWE only officially announced his signing last month.
For what it’s worth, David Arquette was also spotted in Memphis today, PWInsider says, so he possibly may be visiting backstage.
