Mike Phelan has left his position as Hull City head coach with the club in the Premier League relegation zone.
Phelan took charge on a caretaker basis following the departure of Steve Bruce in July, before being handed the reins on a permanent basis in October.
However, Hull have won just one of their last 18 top-flight matches, with Monday's 3-1 defeat at West Brom proving Phelan's final match in charge.
A statement read: "The club can announce this evening that it has parted company with head coach Mike Phelan.
"We would like to thank Mike for his efforts both as assistant manager [to Steve Bruce] and head coach over the last two years.
"The search for a replacement has begun and an announcement will be made in due course."
