Darren Kelly has left FC Halifax Town by mutual consent after just eleven games in charge.
The former Oldham Athletic boss replaced Neil Aspin in October, but has unable to pull Halifax out of the National League Premier relegation zone.
Kelly won three of his games at the helm.
A Halifax statement said: “Notwithstanding a back drop of difficult circumstances and a short time period, it’s been felt that an up-lift in performance and results has not been forthcoming – despite further first team investment.
“Another announcement will follow. “
