Record appearance holder David Matthews, former scrum-half John Allen and ex-prop Bob Beason were presented with specially-commissioned portraits and appeared on the pitch during the interval with chairman Peter Tom and chief executive Peter Wheeler.
Peter Tom said: "David, John and Bob have made an outstanding contribution to the Tigers. All three have provided undoubted service to the club for more than 40 years, first as players, then on the general committee and latterly as directors."
David made a club record 502 first-team appearances, was captain and then coached the side; John played 457 games and for many years was secretary and treasurer as well as a member of the committee; and Bob played 203 games and was instrumental in the creation of what is now the Academy, also serving as president and committee member.
"Clubs like ours depend on the input of so many people at so many levels, and these three have made significant contributions over a long period of time, indeed over a period of time which has seen massive changes in the way the game is played and administered," added Tom.
Peter Wheeler also spoke of their massive contribution and all three received a tremendous reception from a capacity 17,498 crowd.
