Fans have branded the decision to put protective boards around a statue of former Watford manager Graham Taylor "the overreaction of the century".
The club will face local rivals Luton Town for the first time in 14 years on Saturday but no fans will be at the game.
Despite this, the tribute to the late footballing legend near the Vicarage Road ground has been hidden from view.
Watford declined to comment on the reason for its concealment.
As reported in the Harrow Times, the club said on Wednesday it was "fully co-operating with all relevant authorities" to make sure the game passed "safely and securely".
