Hull will display the name of the late Steve Prescott MBE on the front of their away shirt next season, in place of a sponsor.
The Airlie Birds unveiled the purple and black kit, including the Steve Prescott Foundation logo, as part of their 150th anniversary season.
Prescott made 107 appearances for Hull during two spells, scoring more than 600 points.
Set up in 2007, the Steve Prescott Foundation continues to raise funds for the Christie Cancer Hospital, Try Assist and the Oxford Transplant Foundation and the shirt was formally launched by his wife Linzi, and son’s Koby and Taylor, as well as a dozen of Prescott’s former team mates at the KC Stadium.
A donation will be made to the Steve Prescott Foundation from every 2015 Hull FC away shirt sold throughout the year, as well as fundraising at the Steve Prescott Cup fixture against St. Helens.
Steve’s wife Linzi said, “I’m absolutely overwhelmed and I can’t thank Hull FC enough for doing this, it is a great gesture and just shows what Stephen meant to the club.
“Seeing all of the former players here at the Stadium shows just what impact Stephen had on them. They have all turned out and they are all here for Hull FC as well, the club they have played for too so it was brilliant to see them all.
“Now Stephen is no longer around we need a number of players like these and other ambassadors to keep the Foundation going and to keep Steve’s memory alive. They are all putting their hand up and participating in challenges which is just fantastic.
“I hope that the players will be able to take some inspiration from the shirt because I know that Steve is continuing to inspire people even though he is no longer here.
“If he can do that for Hull FC next year I am sure he would be looking down really proud.”
