The Thunder committed 23 turnovers in a 106-101 loss to Sacramento on Thursday.
"It's unbelievable," said coach Scott Brooks, shaking his head at his team's turnover total that now stands at 441 through 26 games.
Oklahoma City leads the league in turnover percentage (the percentage of possessions that result in a turnover) at 16 percent.
"This can't continue to happen," Brooks said.
