The Cleveland Cavaliers have fired second-year coach David Blatt and are replacing him with assistant Tyronn Lue, according to ESPN sources and multiple reports.

The title-hopeful Cavaliers lead the Eastern Conference at 30-11 but were blown out by the defending champion Golden State Warriors on Monday. Blatt had lost support of the locker room over the past month, sources told ESPN’s Brian Windhorst.

Associate head coach Tyronn Lue, Blatt’s top assistant, signed a three-year contract Friday to be the team’s head coach, according to Yahoo! Sports, which also first reported Blatt’s firing.

LeBron James was not consulted before the Cavaliers made the move to dismiss Blatt and was informed of the decision Friday, sources told Windhorst. The decision to fire Blatt was “entirely” up to general manager David Griffin, a league source told ESPN.com.
