Joseph Karl, the 95-year-old father of Milwaukee Bucks coach George Karl, died of natural causes Thursday morning at his home in Marysville, Wash.

Karl left immediately for the Seattle suburb and appointed lead assistant Terry Stotts to guide the team in his absence. Stotts assumed the head coaching duties Thursday night when the Bucks played Toronto.

A date for Karl's return has not been determined. The Bucks play next on Saturday at home against New Jersey.
