The Welshman dislocated his knee cap on March 4th but has since amazed doctors with the speed of his recovery and he is now looking forward to rejoining his team-mates for full training.
"I've been working really hard with the medical team over the last few weeks." Collison told the official site.
"I've had a lot of long days down at the swimming pool and been doing lots of running and hopefully I'll be back in full training on Wednesday.
"I dislocated my knee. It popped out of place. Luckily it wasn't too serious in the end so now I've just got to concentrate on getting back to full fitness. Hopefully I can have one last push at the end of the season."
