Dolph Ziggler passed his "impact" test last night, and has been cleared to return to the ring. We're told Ziggler underwent "impact" testing during the afternoon hours at RAW yesterday but the results weren't revealed until late last night.
Ziggler has been sidelined due to suffering a concussion on SmackDown several weeks ago.
While not official, he is expected to defend the World Title against Alberto Del Rio at the June 16th WWE Payback PPV.
