After firing Adrian Griffin, the Milwaukee Bucks have reached out to Doc Rivers and are engaging him in conversations about the franchise’s head-coaching job, sources told ESPN on Tuesday.

Rivers — an ESPN NBA analyst who led the Philadelphia 76ers to three consecutive trips to the Eastern Conference semifinals before exiting last spring — is the top target of the Bucks’ search to replace Griffin, sources said.

Joe Prunty was promoted to interim coach, a role he’s assuming for the third time in his coaching career — including with the Bucks following the firing of Jason Kidd in 2018.

Griffin had a 30-13 (.698) record, but the Bucks had dropped from fourth to 22nd in defensive efficiency from a season ago, although some of that can be attributed to the loss of All-Star guard Jrue Holiday.
