The cyclist, who won a record three gold medals at last year's Olympics in Beijing, admitted he is still "pretty sore" and does not know when he will be back on the bike .

But he 32-year-old Scot said defending his three world titles - the sprint, keirin and team sprint - he won in Manchester last year still remains his goal.

He said: "Going to the Worlds and defending them - that is my main aim for the season.

"I will be doing everything that I can, but I have got to be realistic and wait and see.

"I'm lucky that I have got a good team and good medical support, but I will still just have to wait and see."

Sir Chris bruised his shoulder and hip during the 40 miles per hour crash in the keirin in the World Cup event, but luckily x-rays showed no broken bones.

His custom-made bike was left a twisted wreck.

He said: "I'm getting better.

"I'm not back on the bike yet. I'm pretty sore.

 

"It could have been a lot worse.

"At the moment, I have no idea when I will be back training and get back on the bike.

"The problem is that there is a lot of swelling, and it is difficult to get a proper prognosis, particularly around the knees and hips, where there could be damage, but it is difficult to see.

"I just need to try and get in shape for the World Championships next month."

With time against him to try to fend off his rivals at the World Championships in Poznan, Poland, he has not yet scrapped plans to compete at a Revolution meeting in Manchester this weekend.

Sir Chris said: "I've not ruled it out completely.

"I have to look forward, because I know things can change really quickly.

"In the space of 24 hours, I have gone from being in a wheelchair to being on crutches, and now I am walking around."
