One of the biggest shocks from the Royal Rumble was Rey Mysterio being a surprise entrant. According to PWInsider, he was close enough to signing a deal with Impact Wrestling that travel plans were being discussed.
Konnan, who has been good friends with Mysterio for decades, started getting involved and the deal fell through. No reason on what the issue was.
There was hope Mysterio would appear at Impact Wrestling’s April tapings, but that seems unlikely considering the pop he got during the Rumble match and WWE wanting to do further business.
