Scots Cyclist Archibald Breaks Wrist
Katie Archibald suffered a fractured wrist on Saturday's second day of the Track World Cup in Glasgow - but won women's Madison gold with Manon Lloyd anyway.
Archibald and Lloyd, on her 20th birthday, tumbled to the track after 18 laps of the 80-lap event before responding to win the first global women's Madison competition.
The 22-year-old Archibald on Saturday evening took to Twitter to post photos of the crash and her visibly injured wrist.
She underwent X-rays at Glasgow Royal hospital on Sunday morning which showed a fracture of her distal radius (forearm) and scaphoid, British Cycling said.
Archibald posted a photo on Twitter of her plastered left arm in a sling.
She wrote: "Rocked up to A&E and told them I need a visually impacting treatment to garner as much sympathy as possible. They delivered.''
She is now scheduled to see a specialist on Monday in Manchester.
Archibald, the Olympic team pursuit champion from Milngavie, north of Glasgow, is the star attraction for the home crowd this weekend.
After winning the two-person relay with Lloyd which features sprints every 10 laps, Archibald wiped away blood from her abrasions before joking about crashes being part and parcel of her job.
"It was a pretty exciting race,'' said Archibald, who got ``a bit of an adrenaline kick'' from the fall.
"Somebody closed down when we came into a change coming into a sprint.
"Someone closed down on top of Manon and I was still there. There was nowhere to go.
"We all came down in a domino, which is kind of a hazard of the trade.
"Something about dangers in the work place. You can say that light-heartedly when we both got back up.''
It is too soon to determine the length of Archibald's absence, but it should not impact on her preparation for next April's Track World Championships in Hong Kong.
But the enforced break will be disappointing for Archibald, who spent much of the 2015-16 track season injured after falling off her motorbike and sustaining a knee injury.
Archibald missed March's Track World Championships in London, but returned to win gold at her first Olympics in the four-rider, four-kilometres team pursuit with Joanna Rowsell-Shand, Elinor Barker and Laura Trott (now Kenny).
The Scot was in good form, having won the omnium at the London Six Day last week, and was keen to entertain her home crowd.
Archibald, the European omnium and individual pursuit champion last month, had initially been entered into the women's scratch race on Sunday's final day of competition at the Sir Chris Hoy Velodrome.
But the UCI, cycling's world governing body, belatedly informed British Cycling that she did not have the required eligibility points to compete.
Emily Nelson was entered instead, while Emily Kay was Britain's entrant in the new-look omnium, which features four bunch races in one day.
Andy Tennant, team pursuit gold medallist on Friday, was seventh in individual pursuit qualifying on Sunday's final day.
Tennant clocked four minutes 22.805 seconds as Daniel Staniszewski qualified quickest in 4mins 18.217secs.
The Polish rider will in the final face France's Sylvain Chavanel, a Tour de France stage winner and yellow jersey wearer. Chavanel clocked 4:20.427.
Detectives say she was subjected to the common assault on Wednesday.
