Radebe snapped his Achilles tendon in only Leeds' third match of the season at Wolves and it was thought his career was over.
But The Chief has made an amazing recovery and the legendary South African captain will make his comeback alongside more than 50 other legends of the game in the 'Football for Hope' benefit at Barcelona's Nou Camp on February 15.
"I will be fit," said Radebe, who is hoping to make a return to the Leeds squad before the end of the campaign.
"At least it's a game where I will be able to tell if everything's all right now with my injuries. It will become part of my fitness programme anyway.
"I have already started doing a lot of running and my rehab is going very, very well. This will be a good test for me because it's really only a practice game and I won't have to worry too much about the injury.
"I have seen the team sheets and there's 28 players on each side, so obviously nobody will get very long to play.
"I think I will probably get about 10 minutes, but that's enough just to show your support for the cause because that's what we're there for."
