Crystal Palace manager Roy Hodgson was furious with Gareth Evans, who wears the Hornet suit on Watford matchdays, after his 'digraceful' provocation of Wilfried Zaha in 2016.
The mascot made a theatric dive in front of Zaha after the winger was booked for simulation.
"I have officially stepped away from being the match day mascot at #watfordfc my decision, proud of what I have achieved, the memories made and the experiences I've had - I was privileged and now heavy hearted also. Love you Harry!" Edwards wrote on Twitter.
At the time of the incident, no action was taken against Edwards, but Zaha reacted angrily before laughing about it later on Twitter.
