Rudy Tomjanovich will step down as coach of the Los Angeles Lakers after tonight's game against the Portland Trail Blazers, sources told ESPN The Magazine's Ric Bucher.
His health, although not a relapse of bladder cancer, and dissatisfaction with the way the Lakers are playing contributed to the decision, sources told Bucher.
Tomjanovich missed Sunday's game because of a stomach virus, and did not attend practice on Monday.
Assistant coach Frank Hamblen will become the interim coach.
The Lakers hired Tomjanovich on July 10, replacing Phil Jackson. They are 23-19, in seventh place in the Western Conference.
Tomjanovich left the coaching ranks over a year earlier to fight bladder cancer. He previously coached the Houston Rockets for 12 seasons, winning NBA championships in 1994 and 1995.
"It's just excitement, nothing but excitement," Tomjanovich said this fall about his return. "It's a positive. I've been like a young school boy since this has happened. At times I haven't gotten to sleep, but it's not anxiety. It's excitement."
After losing to the Detroit Pistons in the NBA Finals, the Lakers ended their successful partnership with Jackson and traded Shaquille O'Neal to the Miami Heat.
