West Wales Raiders have sacked head coach Jon Ellis three days after their record 144-0 Betfred League 1 defeat by York.
Kieren Moss put in a man of the match performance as he scored an incredible seven tries, with his side crossing over 25 times in total.
York lead 60-0 at the break, before posting a further 84 unanswered points in the second-half.
The club have placed Phil Carleton, who coached the club when it was known as South Wales from 2016-17, in temporary charge ahead of Sunday's game at Bradford.
Club chairman Andrew Thorne said: "This has been one of the hardest decisions that the board and myself have had to make.

"Jon has been a stalwart of the club and has helped the club grow since it started in Mynydd y Garreg. However, where we are now and where we need to be, are miles apart.
"Jon is a fantastic coach and has been involved in the development of so many young players for the past eight years, some of whom are in Super League today, but what the club needs at the moment is more than a coach.
"We have to change the culture that is embedded in Rugby League in Wales and to do that we need to look for someone who can manage players as well as coach them."
