Sheffield United Women's head coach Jonathan Morgan is being investigated by the club after a complaint about his conduct.
It is understood Morgan's alleged treatment of certain Sheffield United players was the reason behind a formal complaint being lodged.
Morgan has missed Sheffield United's last three games and has not been present at the club's training ground for several weeks.
The decision to step away from football activities was a mutual one taken by Morgan and the club.
Sheffield United, Morgan and his representatives have not commented while the investigation is ongoing.
Sheffield United are currently ninth in the Women's Championship, taking seven points from their opening six games.
