Panthers Group CEO Brian Fletcher has released the following statement:
"There has been much speculation and rumours about the club and head coach Anthony Griffin over the last few weeks.
"After discussions with Anthony Griffin it is time to end that speculation. By mutual agreement, the club and Anthony have agreed to part ways, effective immediately.
"Anthony departs the club after much success, having taken the Panthers to the finals in the last two years and leaves the club on track for another finals appearance in 2018.
"We would like to thank Anthony for his service to Panthers and wish him well for the future."
