A person with knowledge of the decision tells The Associated Press that Timberwolves coach Rick Adelman has decided to retire after 23 seasons.
Adelman was expected to announce his decision Monday. The person spoke on condition of anonymity because the team had not announced the retirement.
Adelman's career includes 1,042 victories, eighth on the NBA's career list. He coached in Portland and Sacramento and also had stops in Golden State and Houston.
Adelman just completed the third season of a four-year deal with Minnesota. There was a mutual option for the final year of the deal.
After missing the playoffs for the third straight season, and with a wife who is being treated for seizure disorders, Adelman decided it was time to go. He will serve as a team adviser.
