Bradford Bulls have confirmed that they have parted company with head coach Francis Cummins.
Cummins's assistant Lee St Hilaire has also left the club with immediate effect.
The Bulls are currently eight points adrift of safety near the bottom of the Super League table following Sunday's 46-18 defeat at Salford Red Devils.
Cummins, 37, took charge of Bradford in September 2012 after spending two years at the club as an assistant coach.
"This is a decision which has not been made lightly and Bradford Bulls would like to thank both Francis and Lee for their efforts over the years," said a club spokesman.
"Both have worked under difficult circumstances during their time here, but the club recognises that a change of direction is required."
Bradford captain Matt Diskin and managing director Steve Ferres will take temporary charge of the team for their Super League clash with Hull Kingston Rovers on Friday.
