As of right now, there is no word on if Sin Cara or Rey Mysterio will be cleared to wrestle at WrestleMania 28. According to sources, WWE still wants to have one major Latin star on the card. That looks likely as Alberto Del Rio is ready to return once creative comes up with something for him. Obviously, the hope is that Del Rio doesn’t re-injure his groin again from returning too soon.
It should be noted that original plans called for a Mysterio vs. Cara match WrestleMania 28. They were going to try to break the world record for most people wearing masks at once in the same place.
