At first sight I believed New Orleans Pelican star really shaved his unibrow? But after watching a few times, I'm starting to second guess. Here's a clip of the 7 foot phenom making a video of the incident.
Now if you look closely, the camera seems to drop right as Davis appears to be shaving. Once picked up, the unibrow is no more. Something seems a little suspect about this but either way more power to him.
