Titans defensive end Bud Dupree grabbed a man and then wrestled with him for several seconds inside of a Walgreens in Nashville on Sunday night ... new video, obtained by TMZ Sports, shows.
In the footage, you can see the NFL player walk through the doors of the drug store and immediately get in the face of a man near the cash register.
It's unclear what prompted the verbal altercation -- but after exchanging words with the guy, Dupree appeared to try to grab the man's cell phone.
The 6-foot-4, 269-pound pass rusher then forcefully put the man in a bear hug, and all hell broke loose.
