That select band are members of the club’s Hall of Fame and four more will be inducted at a special ceremony on Sunday.
A celebration lunch at Headingley Stadium will also mark the 40th anniversary of Leeds’ 1983-84 JP Trophy-winning campaign.
Players from that team will be in attendance, alongside Hall of Fame members and the current squad.
To be eligible for the Hall of Fame, individuals must have played at least 150 games for Leeds, made an exceptional contribution to rugby in the city and achieved representative honours during their playing career.
