DENVER -- The Denver Nuggets fired coach Jeff Bzdelik on Tuesday on the heels of a six-game losing streak and a lackluster start to the season.
The team scheduled a 1:30 p.m. ET news conference.
"We felt we needed a change. I want to thank Jeff for all the hard work. He's a big part in turning this around," Nuggets general manager Kiki Vandeweghe told the Denver Post. "But we want to build to the next level, and the team wasn't going in the right direction. Sometimes, you can use a change or a new voice."
Nuggets assistant Michael Cooper was named interim coach after Bzdelik became the NBA's first coach to be fired this season. Memphis Grizzlies coach Hubie Brown stepped down last month because of health reasons.
Denver was expected to move near the top of the Western Conference after signing All-Star power forward Kenyon Martin, but so far the season has been filled with bad luck and inconsistency.
Shooting guard Voshon Lenard, Denver's only legitimate outside shooting threat, was lost for the season with a torn Achilles' tendon in the opener and the injuries have been piling up.
The Nuggets started the season without power forward Nene and have used 10 different starting lineups, with star forward Carmelo Anthony missing the past five games with a sprained ankle.
But Denver's problems went deeper than bumps and bruises.
Denver opened the season 2-5, won 10 of its next 12 games and has lost eight of its last nine, dropping to 13-15 after a 104-101 loss to Golden State Monday night -- Denver's sixth straight.
Bzdelik was a longtime assistant and scout under Pat Riley in Miami and New York before getting his first shot at a head coaching job with the Nuggets in 2002. Though Denver struggled to a 17-65 record in his first season, worst in the league, Bzdelik was credited with turning the Nuggets into a hard-working, defensive-minded team.
A roster overhaul and the addition of Anthony made all the difference in 2003-04. The Nuggets improved by 26 games to 43 wins -- the sixth-best turnaround in NBA history -- to reach the playoffs for the first time in nine years.
Through all the success, Bzdelik wasn't able to get any security from the front office. General manager Kiki Vandeweghe refused to give Bzdelik a contract extension last season and it seemed the only reason he was back this year was because of a contract clause that called for his option to be picked up if the Nuggets reached the playoffs.
Bzdelik was 73-119 in just over two seasons with Denver.
Cooper, a member of the Lakers' "Showtime" teams of the 1980s, coached the Los Angeles Sparks to two WNBA championships and a finals appearance in four years before joining the Nuggets as an assistant this season.
Cooper has a two-year contract and an option for a third year with Denver. He coached the Sparks to a 116-31 record.
Denver's next game is Friday against the Philadelphia 76ers.
