Houston, Texas - Rick Adelman won't return for a fifth season as head coach of the Rockets, the Houston Chronicle reported Monday afternoon.
The paper reported that Adelman and Rockets general manager Daryl Morey couldn't reach agreements on how they would continue to work together.
The team did not immediately respond to a message seeking confirmation.
Adelman guided the Rockets to a 193-135 record, including a 43-39 record this past season. The Rockets finished last in the ultra-competitive Southwest Division and missed the playoffs for the second straight year.
After guiding the Sacramento Kings to eight straight playoff appearances, Adelman took a year off when his contract wasn't renewed and was hired by the Rockets on May 23, 2007.
In two decades as a coach for the Trail Blazers, Warriors, Kings and Rockets, Adelman, 64, owns a 945-616 record and ranks eighth on the all-time wins list for NBA coaches.
