Kings guard Aaron Brooks was fined $25,000 by the NBA for throwing his mouthpiece into the stands after the Kings lost at Utah on Friday.
The fine was announced Monday after the Kings' media availability, so Brooks was not available for comment.
Brooks was frustrated after the Kings blew a 13-point lead in the fourth quarter and fell 104-102.
He thought he was fouled by Jamaal Tinsley on a drive with 14.9 seconds to play, but there was no call, and Tinsley was credited with a steal.
Brooks is the third King to be disciplined by the league this month.
Forward Thomas Robinson was suspended for two games for a flagrant foul against Detroit's Jonas Jerebko, and center DeMarcus Cousins was suspended for two games for leaving the locker room to confront San Antonio television analyst Sean Elliott after a game.
Injury report Guard Marcus Thornton (strained right quadriceps) left practice early and will be re-evaluated today to assess his availability for tonight's game against Minnesota.
Forward-center Chuck Hayes left practice early after being poked in the left eye. Hayes received stitches near his right eye during Wednesday's win over the Los Angeles Lakers when he and teammate Jason Thompson bumped heads.
He's back The Timberwolves beat the Kings on Nov. 2 without All-Star power forward Kevin Love, who broke two bones in his hand Oct. 17.
Love is averaging 24.3 points and 14.0 rebounds in three games since returning.
"He's going to bring the rebounding, the effort and the ability to shoot the basketball," Kings coach Keith Smart said.
Love made just 6 of 20 shots in scoring 15 points in Saturday's loss to the Warriors, but he had a season-high 15 rebounds.
