Radebe said: "If the gaffer wants me to be involved then I'm ready to be in the squad and hopefully play on Saturday.
"I've stayed positive. All the time I've made sure I'm like that and I think that's what helps me to heal a lot quicker. I've also done a lot of hard work in training, a lot of swimming and it feels much better."
Striker Robbie Fowler should also be available for the game at Loftus Road after playing for 63 minutes in the same game and he is now close to full fitness after his hip injury.
