WWE’s website has a storyline article up about who planted the cinder blocks that were used to take out Dean Ambrose on RAW. Michael Cole noted on Main Event that Kane was responsible and Seth Rollins told the website:
“They call me the ‘Architect of The Shield’ for a reason. I put everybody together and was responsible for all the faction’s success – as well as the success of Dean Ambrose. Now, I am the one who has has torn it apart. On the other side of things, there’s Director of Operations Kane, who has been around a long time and is also very smart. You put a mind like [his] with a mind like mine, who knows what could happen. So, when it was the right time, the cinder blocks were revealed and the plan played out perfectly.”
