Broken arm is probably about six weeks. So no WM for Barrett. But what was he going to do at this point anyway? His biggest feud is injured indefinitely (Orton), other than that he might have ended up in the MITB, or been involved with ADR/Henry/Christian. Hopefully this gives them a chance to prep him for something big.
Smackdown needs faces. They have Barrett/DBD/Henry/Cody/ADR/Christian. Six good heels vs. Sheamus/Orton/Show. Something has to change there.
