According to The Wrestling Observer Newsletter, Rey Mysterio's son Dominick Gutierrez may return to WWE storylines soon. It's said that officials would like him to wrestle and the current storyline with the Master of the 619 could result in that happening.
The 21 year old started training to become a pro wrestler last year and has received guidance from Lance Storm. While the feeling right now is that he's not ready for in-ring action on a stage like WWE, the hope is that will change by next year. On Monday's RAW, Mysterio suffered a big loss to Andrade and he was then shown backstage extremely upset and talking about supporting his family.
WWE has seemingly scrapped plans for Dominick on a number of occasions and the idea of him being in Rey's corner at WrestleMania was nixed last-minute.
