Nets coach Avery Johnson was fired Thursday, his team having lost 10 of 13 games after a strong start to its first season in Brooklyn.
"We don't have the same fire now that we did when we were 11-4," general manager Billy King said during a news conference in East Rutherford, N.J.
Assistant P.J. Carlesimo will coach the Nets (14-14) on an interim basis. King would not comment on a report that the team planned to contact former Lakers coach Phil Jackson.
Johnson was in the final year of a three-year, $12 million contract. "I didn't see this coming," he said.
