Leicester City have printed 30,000 Jamie Vardy masks for their Boxing Day game with Everton to show their support to the banned England striker.
Vardy is serving a three-match suspension after being sent off at Stoke on 17 December for a two-footed challenge on Mame Biram Diouf.
Leicester's appeal against the ban was rejected by the Football Association.
In an Instagram post, Foxes owner Vichai Srivaddhanaprabha said the decision was "unfair".
FA chairman Greg Clarke is set to attend the game at the King Power Stadium on Monday.
The Premier League champions have won only four of their opening 17 league games of the season and are three points above the relegation zone.
