Disaster for Hong Kong’s medal hopes at Olympics as Sarah Lee Wai-sze crashes out of keirin semi-finals after controversial clash

Hong Kong's Sarah Lee Wai-sze suffered disaster in the semi-finals of the women's keirin in Rio on Saturday, crashing with less than a lap to go as she jostled for position.

Lee, who won bronze in the same event at London 2012, was ideally placed as the pack rounded the turn at 60km/h-plus, but was nudged by Australia's Anna Meares and lost control of her front wheel in a painful looking crash.

It means Lee misses out on a place in the final, having been one of the most impressive qualifiers for the semis in winning her heat.

The 29-year-old still has one medal hope left, in the sprint on Sunday, but the keirin is her preferred event.

Lee easily won the 7th-to-12th race, underlining her class and the missed opportunity.

Clearly disappointed afterwards, Lee said she wasn't too badly hurt, and chalked the crash up to “one of those days” as she focuses on a medal in her second event.
