Ipswich Town will carry the logo of the East Anglian Air Ambulance charity on the back of their shirts next season.
As part of the deal, the charity's logo will be visible on both the men's home and away kits and the ladies team will also carry it on their shirts.
The East Anglian Air Ambulance has attended more than 25,000 life-saving missions since its inception in 2000, and Prince William recently worked for them.
They also helped to save the life of Ipswich academy coach Shaun Whiter who lost both of his legs in a hit and run crash in 2016.
"These guys saved my life that night. I will always be grateful for that," Shaun told the club's official website.
"We're a community club and to work with such an inspirational charity is a real honour."
Ipswich fans will also be able to add the charity’s logo to their replica shirts for a nominal fee, and all proceeds will go to the East Anglian Air Ambulance.
The club introduced the addition of a charity sponsor back in 2017, with East Anglia’s Children’s Hospices being picked as the chosen partner for the past two seasons.
