Former Sheffield United captain Chris Morgan is swapping 90 minute games at Bramall Lane for a 12-hour walking football match.
He has volunteered to take part in the game alongside boxer Glyn Rhodes, council Leader Julie Dore, paralympian Will Bayley, recording artist Paul Pashley and artist Pete McKee.
There are 10 other places up for grabs.
The event, which takes place at Hillsborough Leisure Centre from 9pm on Friday, June 5 to 9am on Saturday, June 6, has been organised by former Premier League referee, Uriah Rennie, to raise cash for St Luke’s Hospice in Whirlow.
Uriah Rennie, community liaison manager at Sheffield City Trust, a charity which provides sport and leisure facilities and works to promote health and wellbeing in Sheffield, said: “I’m delighted to see some of the region’s best known names put themselves forward to take part in this event and raise money for such a worthy cause.
“One of the greatest things about walking football is its inclusiveness - it allows people of all abilities and ages to take part and it doesn’t require any past experience of playing football - which makes it the perfect charity event.”
Walking Football has the same rules as five-a-side football, but players can only walk.
It is a non-contact sport and anyone that sprints, runs or jogs while the ball is in play will be penalised with a free-kick awarded to the other team.
Participants will be able to play for the entire 12 hours or for as little as five minutes.
