Assistant coach Joe Prunty was serving as head coach for Monday night's game against Phoenix.
"We appreciate everything that Jason has done for the Bucks organization, but we have decided to make a coaching change", Bucks General Manager Jon Horst said in a statement released by the team.
Jason Kidd, a former National Basketball Association star, helped steer the young career of Giannis Antetokounmpo.
There wouldn't have many Milwaukee Bucks fans at the start of the season who'd have expected their team to be in a battle to make the playoffs over halfway through the season, yet that's where the Bucks find themselves.
Sam Amick of USA TODAY reports that former New Orleans Pelicans coach Monty Williams is a "name to remember" for the now-vacant Bucks position.
The Bucks were 139-152 under Kidd over four years and made the postseason twice. The news also came as a surprise then to Drew.
Kidd last week blamed the lack of results on a shortage of experience. We're going to be a team that wins two and loses two.
The Bucks have been up-and-down this season despite a career year from Giannis Antetokounmpo and a trade for Eric Bledsoe that was supposed to take them up a notch.
And there are few more attractive jobs than Milwaukee, where Antetokounmpo is a generational talent improving in each of his first five seasons.
