The Phoenix Mercury fired assistant coach Todd Troxel on Tuesday after an investigation into an alleged domestic violence incident.
Troxel, 41, was charged with misdemeanor assault and disorderly conduct stemming from a "physical altercation" in his home on Nov. 30.
"We have determined that Troxel's conduct on that night was unacceptable and does not represent our values as an organization, and we cannot continue his employment," the team said in a news release.
Troxel had been a Mercury assistant coach for five seasons.
The team began the investigation after being alerted to an incident involving Troxel and his fiancee by a media report. The team retained an outside firm to conduct an independent investigation that included interviews with both parties.
Troxel went to the hospital following the altercation with serious cuts to his hand, while the woman, who called 911, suffered a minor injury to her hand.
Lt. Michael Cole, a spokesman for the Paradise Valley police, said the incident started as an argument that later turned physical.
"We recognize domestic violence as a significant problem," the Mercury's statement said. "Our league, our team and our staff are committed to our mission of uplifting women, being an inclusive and safe space for all, and inspiring the next generation."
