As noted earlier here on WrestlingNewsWorld.com, Rey Mysterio did ambassador work for WWE at Hulu Upfront on Tuesday. The former WWE Champion is currently out with a left knee injury after dealing with undisclosed personal issues.
Mysterio has racked up the injuries over the past couple years, suffering a badly torn ACL in 2011 that kept him off television for nearly a year. Once he did return, after his second Wellness policy suspension, he suffered a concussion at SummerSlam 2012.
In March, Mysterio was examined by Dr. James Andrews in fear that he suffered yet another ACL tear. It turns out his knee didn't require surgery and he's been trying to rehab the injury wearing a Dynamic Knee Splint. WWE had their doctors examine him backstage at WWE Raw earlier this month and Mysterio is hoping to return to the ring some time this summer.
