The Detroit Pistons' lousy season somehow just got even lower ... the team's GM, Troy Weaver, was filmed getting into a heated spat with an angry fan at a game on Saturday.
The incident reportedly happened in the fourth quarter of Detroit's blowout loss to the Dallas Mavericks at the Little Caesars Arena ... when a man decked out in Red Wings gear seemed to confront Weaver at his seat.
You can see in a video posted to TikTok on Sunday ... Weaver appeared to yell at the fan, "You're lucky I don't beat your ass" -- before the man can be heard responding, "You suck at your job."
Weaver then motioned for a security guard to take the guy away from the area. The video then cut out.
A season ticket holder who claimed to have witnessed the interaction told the Associated Press on Sunday the tiff was actually the second time the man had gotten into it with Weaver at the game.
"The guy that was in the incident, with the Red Wings stuff on, came over and was pointing at the scoreboard earlier in the game,” Jeffrey Calloway told the AP. "Troy Weaver just shrugged his shoulders and said, ‘OK,’ and the guy went back to his seat."
"When [Jalen] Duren got ejected, the guy came back and told him that he was terrible at his job. Then, Troy Weaver was telling the fan he had to leave and that's when ushers or security walked over."
Weaver -- Detroit's GM since 2020 -- has yet to publicly comment on the matter.
The Pistons, meanwhile, currently hold the worst record in the NBA at 10-53. They're slated to play next on Monday night against Charlotte.
