Sacramento Kings guard Dennis Schröder has been suspended three games by the NBA for something that happened behind closed doors.

The league announced the punishment out of the blue on Saturday, alleging that Schröder had confronted and attempted to strike another player following the Kings' loss to the Los Angeles Lakers on Dec. 28. Per the league, Schröder sought out the unidentified player in a Crypto.com Arena hallway and initiated a confrontation.

According to Prime Video's Chris Haynes, that player was Luka Dončić.

The suspension will begin with the Kings' game against the Houston Rockets on Sunday. It's unclear if Schröder is appealing or has already appealed the decision.

That Lakers game won that game 125-101, breaking a three-game losing streak against a Kings team currently sitting in last place in the Western Conference at 8-30. 

While the NBA does not specify the other player involved, Dončić was the educated guess even before Haynes reported his identity. Schröder and Dončić were exchanging trash talk during the game and the Lakers star targeted what might have been a sore spot for Schröder.

Schröder has had two tenures with the Lakers. In the first, he was brought in to be the team's starting point guard and eventually left in free agency after a disappointing postseason. 

It has been claimed that during the season, Schröder turned down a four-year, $84 million extension offer for the Lakers to test free agency. If that's true, the bet on himself didn't pay off, as went on to sign only a one-year, $5.9 million deal with the Boston Celtics. Over the next four seasons, he made a total of approximately $34 million in salary from seven different teams, per Spotrac's numbers.

Schröder has persistently denied any such offer was made, but the story has followed him ever since. And Dončić went right for it last month.

Apparently, Schröder had a problem with that.
