We reached back out to Flair's rep -- so far, no word back.Ric Flair was treated for a cut on his hand at Logan International Airport in Boston Wednesday morning ... but witnesses say it was the culmination of a very bizarre morning involving the WWE legend.
Here's what we know ... Flair hit up Lucky's Lounge in the airport before his flight -- and multiple witnesses say Flair was acting like a drunk person.
One witness says Flair was loud and obnoxious. Another witness says he was "having a tough time" and "shambling about."
But we spoke with Airport Police Sgt. Donlon who tells us Flair was NOT intoxicated.
Sgt. Donlon says airport officials got a call for a "man with a cut on his hand" -- and police and medical personnel responded. Flair was treated -- deemed not drunk -- and was allowed to get on his flight.
We spoke with Flair's rep who told us Ric is fine -- and made his flight.
As for how Flair injured his hand -- we're working on it.
9:43 AM PT -- Ric's agent, Melinda Morris Zanoni, tells us she has spoken with Flair and issued the following statement:
"Ric has been working every day around the clock, including internationally, for a month straight and has injuries on his hand that were being looked into this morning."
"While it is true Ric Flair and his buddies have been keeping airport bars in business since the 70s that was not the case at all in Boston. I just hung up with Ric, he is already on the flight and all is good."
