Watford have designated Saturday's home Championship fixture against Millwall as this season's Graham Taylor Matchday in memory of their former manager.
Fans from both sides are being asked to bring scarves to Vicarage Road to hold up as the teams come out onto the pitch before the 12:30 GMT kick-off.
And there will be 60 seconds of applause in the 72nd minute to mark Taylor's death at the age of 72 in 2017.
First brought to the club by Sir Elton John in 1977, Taylor led Watford to four promotions in five years before leaving for Aston Villa - and two further promotions followed after he returned to the club in 1996 following a spell as England boss.
