Matt Diskin will leave his role as Batley coach with immediate effect.
The 37-year-old took charge of the Bulldogs in 2017 and guided the club to the Championship Shield semi-finals in his first season.
But the club have struggled in 2019, finishing 10th in the Championship table. Diskin’s assistant Lee St Hilaire will also depart the Bulldogs.
In a statement released by Batley, it read: “Matt’s effort and commitment to the club cannot be questioned and he leaves a legacy of improvements, including the new gym, which he was a driving force for after taking charge of the team.
“Through the recent post difficult times off the field, Matt has been a credit to the club and himself in the way he has handled the situation.
“He will leave with our sincere thanks and appreciation for all he has done at Batley Bulldogs.
“As with Matt, our thanks and best wishes to go Lee for his outstanding work and professionalism over the past three years.”
