Randy Wittman will not return as Washington Wizards head coach next season.
The Wizards announced the end of Wittman's tenure on Thursday following a season in which they missed out on the postseason having made it to the second round of the playoffs in each of the last two years.
"There were high internal and external expectations for this team coming into this season based on the momentum we had generated over the previous two years," Wizards president Ernie Grunfeld said in a release.
"Unfortunately, the inconsistency of the team's performance and effort, particularly on our home court, did not allow us to meet those expectations and we decided a coaching change was needed."
The Wizards finished 41-41, putting them 10th in the Eastern Conference, and went 22-19 at Verizon Center. Overall, Wittman was 178-199 in the regular season and 12-9 in the playoffs after taking over for Flip Saunders in January 2012.
Meanwhile the Sacramento Kings have fired their head coach George Karl.
Karl went 44-68 in a season-and-a-half after he took over for Tyrone Corbin during All-Star break last campaign.
"After evaluating the team's performance this season, I determined it was necessary to move forward with a new voice from the head coaching position," vice president of basketball operations and general manager Vlade Divac said.
"I have a great deal of respect and admiration for George and his accomplishments throughout his nearly 30 years in the NBA. On behalf of everyone in the Kings organisation, I thank him for the contributions made during his time in Sacramento and wish him good fortune in the future."
