4:21 PM PT -- OBJ's attorney, Daniel Davilier, is saying this a huge misunderstanding ... on the part of the airline. In a statement, Davilier insists his client wasn't going in and out of consciousness -- like cops said they were told he was -- but rather ... the dude just fell asleep.
Davilier says Odell had dozed off after boarding the flight. Soon enough, DD says Odell was awoken from his slumber by the crew ... telling him he had to get off the plane 'cause he hadn't put his seatbelt on, something that was apparently communicated to him while he was out. Davilier says Odell had no problem complying with the order once he was aware of it, but at that point ... he says an overzealous flight attendant told him it was too late.
Davilier says the attendant wanted to flex his authority and completely blew this out of proportion. Plus, he claims the airline, American, sent his luggage to L.A. without him.
Odell Beckham Jr.'s free agency is off to a rocky start -- the guy was yanked from an airplane this weekend in Florida ... this after cops say he was passing out before takeoff.
The famed wide receiver was escorted off a flight Sunday that was leaving the Miami airport for L.A. ... but it never got off the runway, because law enforcement's saying they had to step in when OBJ was allegedly freaking out the flight crew with his loopy state of mind.
Miami-Dade PD says they were called to respond to an American Airlines flight, where attendants were apparently trying to get Odell to buckle up before they hit the skies. However, according to cops, the crew claims he was in and out of consciousness.
American called first responders, as they were worried for his health ... but when the cavalry arrived, Odell is alleged to have refused to get off the plane -- which forced everyone else to deplane, before OBJ finally walked off on his own with uniformed officers in tow.
Odell was quiet as he made his way through the airport ... with onlookers recognizing him immediately. Cops say he did all this without further incident and was able to make other arrangements in the end. Nothing else came of it ... including arrests/citations and the like.
The dude's supposed to start making visits all over the country in the coming days to see which teams might wanna try swooping him for their roster.
