Former WWE World Heavyweight Champion has undergone surgery on his right knee for the torn ACL/MCL/meniscus he suffered at a WWE live event in Dublin, Ireland last week. Rollins had the surgery in Birmingham, Alabama on Tuesday. A photo gallery on WWE.com shows 27 photos of Rollins going in for the operation in Birmingham, Alabama - from the time he got out of his car to when he was knocked out while doctors performed the operation. Some of the photos are pretty graphic... What's also evident from the photos is that WWE cameras were on hand to document the whole thing. It's likely that they will be filming a lot of his rehab as a way to build up his return in 6-9 months via video packages and perhaps there could be a WWE Network special dedicated to it. Rollins posted the following on his personal Facebook page: "Huge thanks to everyone who has reached out and extended their support over the last week. Means a lot to me. Surgery is done and I'm on the mend! Every day is forward movement now. I'll be back at it before you can even miss me." WWE also posted a video of an injury on their Youtube channel. It looks like they are different views from fans that posted videos online. https://www.youtube.com/watch?v=kcwqSJLNrOE As you can see in the video, Rollins got hurt trying to do a Powerbomb on Kane. Even after the injury, he still completed the move, which shows how tough he is. https://instagram.com/p/92X8tfOU4J/
