Rider suffers unusual injury in crash
Malaysian rider Azizulhasni Awang has undergone surgery to remove a shard of wood from his leg on Sunday after a crash at the World Cup on Saturday.
As Sir Chris Hoy surged to victory in the keirin final in Manchester, carnage unfolded behind him with four of the six riders wiped out on the final bend.
Awang's calf was pierced by a 20cm splinter but he got up to win bronze.
Awang tweeted on Sunday: "Operation done. Splinter taken out cleanly. Thanks for the prayer and support."
The 23-year-old has been ruled out of the World Championships, which begin on 23 March in Apeldoorn, Netherlands.
A scan late on Saturday night at Manchester's Royal Infirmary assessed the injury but medics opted to wait to tackle the shard of wood.
Malaysia head coach John Beasley said: "They said it's best if they do it with all their experts around and when everyone's fresh.
He'll be right for the Olympics. Hopefully Sir Chris Hoy will be in second place and he'll be on the top

"The only way they can do it is by surgically going in from both ends and spreading it apart and pulling it out."
Awang, who has won World Championship medals in the last two seasons, had attempted to squeeze through a gap and appeared culpable for the crash, which also resulted in Australia's Jason Niblett, Kamil Kuczynski of Poland, Edward Dawkins of New Zealand and Spain's Juan Peralta Gascon being knocked off their bikes.
A foot race to the line ensued in an attempt to gain valuable Olympic qualification points, with bloodied and bruised Niblett taking silver.
Beasley was unaware of the splinter and helped Awang back to his bike, having checking the rider's head and state of mind, but not assessing his body for injuries.
"I feel really bad because I didn't even see it," added the head coach, who said adrenaline probably took Awang across the line.
"It wasn't until later I knew he had the splinter."
After being stretchered away, Awang was unable to receive his bronze medal on the podium, with Kuczynski fourth, Dawkins fifth and Peralta Gascon last after forgetting to carry his bike to the line.
Beasley added: "He'll be right for the Olympics. Hopefully Sir Chris Hoy will be in second place and he'll be on the top."
Awang was not due to ride in Sunday's team sprint, with the Malaysia team of Muhamad Edrus Md Yunos, Josiah Ng Onn Lam and Hafiz Sufian set to ride in qualification.
