Over 100 former team mates will be on the pitch along with members of the Holmes family and the Leeds Board of Directors to join both teams in a minutes silence. The Leeds supporters will pay their own tribute by holding up blue and amber scarves in memory of the man who played 625 games for the club in four different decades.
The club has also arranged for the 1978 Challenge Cup Final, in which Holmes played a key role, to be shown on Sky's big screen from 6pm, and the matchday magazine has been given over as a tribute to the man who was part of Great Britain's World Cup winning squad in 1972.
Looking ahead to the game McClennan said, "It will be an emotional night for the club and we have spoken about John Holmes a couple of times this week in our meetings. To have played 625 games for the club, played in 19 Finals and won 14 of them is an incredible achievement and something that we are all proud of.
"We are just the current guardians of the blue and amber jersey and hopefully we can produce a performance on Friday night that does John's memory justice."
Fans can still buy tickets for the game at www.therhinos.co.uk/buytickets or they can pay on the night at the turnstiles for all areas of the ground.
