Shawne Merriman — Appeared Incredibly Sober … After Alleged Medical Emergency

Exclusive 061013_shawn_merriman_launchFor a guy who was allegedly hospitalized at 9:30 pm Sunday night, retired NFL star Shawne Merriman appeared incredibly SOBER when our sources shot him out just 3 hours later.

The whole situation is bizarre … considering law enforcement has confirmed with that the former NFL All-Pro was transported to an L.A. hospital for an undisclosed “medical emergency” around 9:30pm Sunday night.

In fact, law enforcement sources tell our sources … officials responded to a “possible overdose” at Colony nightclub with a caller reporting a man who was “barely conscious.”

Sources tell us … the 29-year-old former NFL All-Pro had been inside the club — but was “escorted out” after people inside believed he appeared like he was going to pass out.

Which brings us to the video …

Our our sources photog noticed Merriman leaving Greystone Manor (a short cab ride from Colony) around 12:26am on Monday morning … and struck up a normal our sources conversation with the guy.

In the footage, Merriman appears lucid, conversational … and in no way like a person who was “barely conscious” just 3 hours before the video was shot.

At one point in the video, Merriman asks us “So, what”s up” Our guy responds, “Just livin”.”

Merriman quickly jokes back, “Yeah, me too.”

Plus, Merriman was tweeting around 2:40 am … telling people he was partying with rapper The Game.

So, what REALLY happened Sunday night Seems the jury is still out.
