Pistons’ Isaiah Stewart appears to threaten NBA vet

Detroit Pistons and Milwaukee Bucks players got into a heated incident in the third quarter of their matchup on Wednesday night.

Pistons center Isaiah Stewart came face-to-face with Milwaukee Bucks veteran Bobby Portis as Detroit led by seven points. As the two jawed at each other, Stewart showed his fist to Portis, possibly signaling that he was going to give the 11-year pro a knuckle sandwich.

Portis seemingly declined and players from both teams came over to break up the action before it escalated.

Stewart was hit with his second technical foul of the game and was promptly ejected. Portis also received a technical foul.

Stewart was still irate as he went back to the bench. He told his coach, JB Bickerstaff, that once the game was over he was “going to punch (Portis) in his s—.” The promise seemingly went unfulfilled.

Milwaukee came back to win the game, 113-109. Kevin Porter Jr. led the way with 26 points. Portis had 13 points off the bench.

Giannis Antetokounmpo left the game with a calf injury amid rumors that he could be traded. He only played three minutes.
