A person with knowledge of the decision says Timberwolves coach -- and former Sacramento Kings' coach -- Rick Adelman has decided to retire after 23 seasons.
Adelman is expected to officially make the announcement later today. His 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.
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.
