Regarding Chris Hero being signed by WWE, officials wanted to sign him a few months back when they signed his partner Claudio Castagnoli to FCW. Hero was going through the physical screening process. It’s believed that either WWE found something they wanted to take their time on double checking to make sure he’s fit to sign, or they stalled in contract negotiations.

Hero hasn’t gone back to work for NOAH or ROH yet so it’s still possible he will pop up in FCW soon.
