EXCLUSIVE

Ex-NY Jets cornerback Dee Milliner -- who was cut from the team last month -- was involved in an early morning bar brawl in Alabama over the weekend ... TMZ Sports has learned.

Millbrook PD chief P.K. Johnson tells TMZ Sports ... Milliner was at Dooley's Pub when a fight broke out early Saturday morning. Cops were called to the bar for a "large scale disturbance" at 3:56 AM.

According to Johnson, the bar staff had asked a patron to leave -- but the person refused -- and got violent while being escorted out.

Johnson would NOT verify if that patron was Milliner.

However, we're told Milliner was at the bar at the time and allegedly involved in the brawl in some capacity.

We're told 2 people were hospitalized with minor injuries. Other people suffered light wounds. No arrests were made. Most people left the scene when cops arrived.

At this point, no one seems to be pressing charges.
