Chief scout Malcolm Crosby and goalkeeping coach Mike Pollitt have left Wigan Athletic following the sacking of manager Gary Caldwell.
Caldwell departed on Tuesday after 18 months in charge, with the club 23rd in the Championship after one win in 12.
The Latics have placed assistant manager Graham Barrow and development squad manager Peter Atherton in charge for Saturday's trip to Cardiff City.
They will be assisted by first-team coach Joe Parkinson.
Pollitt had been with the Latics since 2005 - making 52 appearances as a player before retiring in 2014 - and was initially appointed as a coach by Uwe Rosler.
Caldwell, meanwhile, released a statement via the League Manager's Association on Thursday.
"I am obviously really disappointed to leave after almost seven years at the club," the former defender said.
"It was Wigan who gave me a start in my coaching career with the academy and I owe a debt of gratitude to the chairman.
"I am fully aware that the results haven't been good enough this season but, having not lost by more than one goal all season, I truly believe we are not far away.
"There is a great squad of players who have and will continue to give everything and I am confident they can progress this season."
