WWE Legend Scott Hall -- BOOTED FROM WRESTLING EVENT ... Allegedly Hammered, Again

WWE Hall of Famer Scott Hall was physically escorted out of a wrestling event in NJ this weekend ... after promoters say the recovering substance abuser was way too hammered to do his job.

Hall has battled drug and alcohol issues for years ... but had teamed up with some other wrestling legends in recent years in a public effort to clean himself up.

Which is why the people at the Skate and Surf Music Festival in Asbury Park, NJ were so disappointed Saturday when Hall appeared to be wasted ... hours before he was supposed to host a meet and greet with fans.

According to our sources, Hall was given multiple chances to sober up ... but never did. Organizers told Hall to leave ... but he refused, demanding to be paid.

Eventually, security stepped in and escorted Hall off the property.

The event promoter, Ricky Otazu, tells TMZ Sports, "The event was too well run for us to make a fool of ourselves by allowing him to appear. We will no longer be associated with him until he gets his life in order."

Hall was arrested in 2012 for allegedly choking his girlfriend during a drunken rage and was sentenced to 10 days behind bars for a 2010 DUI arrest.

We made several efforts to reach Hall for comment -- and even called his close friends and family members -- but so far, no word from the wrestling star.
