Fabrice Muamba will present the Capital One Cup to the winning captain in Sunday's Wembley final between Swansea and Bradford.
The 24-year-old will be the sponsor's guest of honour for the day and will also watch the game from the Royal Box, as well as being introduced to the squads before the game.
The former England Under-21 international was playing for Bolton in an FA Cup quarter-final against Tottenham last March when he suffered a cardiac arrest and collapsed.
The midfielder's heart stopped beating for 78 minutes but because of the prompt treatment he received on the pitch he defied the odds to survive and make an incredible recovery.
Although he hoped to resume his career, he was advised against it by doctors and retired from the sport in August.
Capital One will also be making a donation to the Hearts and Goals campaign, which is involved with aiming to raise awareness and give communities across the country access to defibrillators, as well as CPR and defibrillator training.
Muamba, who is involved with the charity, said: "It's been such an exciting tournament this year and it will be a great honour to be presenting the trophy to the winners. I know it will be a very special atmosphere on Sunday."
