Oliveira crumbled to the mat following a takedown attempt. The fight was waved off after just 99 seconds, but the cause for concern didn't end there. According to MMAJunkie's Matt Erickson, Oliveira was put into a neck brace and was stretchered into the back following the fight.
Not a good looking scene here with about a dozen people gathered around Oliveira as they stabilize his neck and get him on a stretcher.

Oliveira's neck is braced, and he's on the stretcher. They're taking him out the back way and he's still grabbing at his neck.
