Former NBA All-Star Terry Porter is out as Portland's head coach, sources told ESPN on Friday.
Assistant coach Ben Johnson will take over on an interim basis until the end of the season. An official announcement is expected soon.
Porter has been the Pilots' head coach since 2016, and has struggled to turn the program around since taking over for Eric Reveno. Portland hasn't won more than four West Coast Conference games in a season under Porter and the Pilots have won just one conference game over the last three seasons.
Porter, who spent 17 seasons in the NBA, was a two-time All-Star with the Portland Trail Blazers.
