The Milwaukee Bucks are firing first-year head coach Adrian Griffin, sources told ESPN's Adrian Wojnarowski on Tuesday.

The Bucks are planning to quickly pursue a small pool of accomplished and available veteran head coaches -- with Doc Rivers near the top of the list, sources said.

Veteran assistant Joe Prunty is expected to take over as interim coach, sources said. Milwaukee next plays host to Cleveland on Wednesday.

Milwaukee hired Griffin over the summer to replace longtime coach Mike Budenholzer, who was fired after Milwaukee's first round exit last postseason.

Milwaukee enters Tuesday night's slate 30-13 and No. 2 in the Eastern Conference.
