Tennessee Titans linebacker Bud Dupree just pled guilty to a misdemeanor assault charge stemming from his role in a fight at a Walgreens earlier this year, TMZ Sports has learned.

The 29-year-old football player -- according to a court official -- appeared in a Nashville, Tenn. courtroom on Monday and made the plea after striking a deal with prosecutors.

Dupree pled guilty to misdemeanor assault offensive or provocative, the court official tells us.

Dupree was sentenced to unsupervised probation for 6 months, according to the official. He also had to pay $418 in court costs.

The Titans had practice Monday morning ... though it's unclear if the pass rusher -- who signed a 5-year, $82.5 million contract with the Titans in 2021 -- made it to the workout.

As we previously reported, Dupree was initially cited back on Jan. 4 after cops say he attacked an employee at a Nashville-area Walgreens on Jan. 2.

Cops say Dupree grabbed the employee during the incident -- and then attempted to take the man's phone, before eventually fleeing the scene prior to police officers' arrival.

Sources close to Dupree allege the employee had heckled the Titans player ... and threatened to spit on the women he was with, inciting the fracas.

We've reached out to the Titans, Dupree's attorney, and prosecutors for comment, but so far, no word back yet.
