Bluebirds fanatic Jayne Hughes has organised a football match between supporters who use Annis Abraham's Message Board (AAMB) and those that post on Mike Morris' board (CCMB) in aid of the Fred Keenor Statue Fund Appeal.
It kicks off at 2pm on Sunday, August 22, on the under-16's pitch at Leckwith, opposite the Cardiff City Stadium.
Jayne, who is from Caerau, Ely, said: "Ex-City stars Damon Searle and Scott Young have agreed to act as managers for the two teams.
"A great fun day for all is promised with music from Wiggy of Real Radio, a raffle with some great prizes and activities for children including a penalty shoot, and it's all for a good cause. We'll be there from 1pm." City half-time announcer Wayne Crichton has also accepted an invitation to attend.
Team photographs will be taken at pitch side at the stadium before the game with the sides having use of the changing rooms. The Premier Lounge (Level 4) will be after the game for the presentation of trophies and the raffle draw. Each competing player is contributing £20.
Statue fund project manager David Craig said: "We thank Jayne so much for her great work in putting together this event in aid of the fund. We hope that other supporters will follow her lead and organise their own events - it can be a jumble sale, coffee morning, whatever you want to do."
On the day players will shower and change at the ground and have a tour of the stadium. Half-hour tours for everyone else are available starting from 4pm and running until 5.30pm. The cost is just £2 for adults and £1 for children.
