During the NXT Takeover: [R]Evolution pre-show, Corey Graves showed up and indicated that due to numerous concussions received, the WWE doctors have suggested to him to retire from the ring. He took their advice and announced his in-ring retirement.

However, even with that being said, Corey Graves is still going to remain a WWE employee by joining the NXT Commentary.

Had legitimate main event potential. Big, big blow for the WWE.

D:

Take some headache pills and get back in that ring!

That sucks for him, but we'd heard that this was a likely possibility a few months ago. I think he'll be fine on NXT commentary, maybe he can take Riley's place so Alex can have another go in the ring.

I'd heard he was also helping with some of the performance center training, so maybe he can continue doing that as well.

This dude was one of the biggest heels on NXT. Such a shame.
