Laura Kenny suffered a nasty eye injury when she crashed in the omnium at the UCI Track Cycling World Championships in Berlin.
She hit the velodrome hard just before the final lap of the opening scratch race, leaving her with a black eye and four stitches.
Kenny broke her shoulder in the same event in the final round of the Cycling World Cup in Canada last month.
Her shoulder was spared the worst of the impact she was back on her bike for the tempo race.
Kenny could not force her way back into the medal reckoning as Yumi Kajihara became the first woman to win a track world title for Japan, but a strong third place in the final points race moved Kenny up to 12th overall.
“I should probably stop headbutting the floor, shouldn’t I?” said Kenny, omnium champion at the past two Olympics. “It’s just been one of those months. One to forget.
“But Sir Chris (Hoy) just spoke to me and said: ‘You know what, in six months time this will all be forgotten.’ And he’s right. It just wasn’t my day today. But I’m glad I got back up and raced. I came here to race. Rightly or wrongly.”
Kenny was caught up in a big spill just before the bell to start the final lap of the scratch race as five riders hit the deck.
She received lengthy treatment at the side of the track before going through a concussion check, but was sure she wanted to continue.
“Instantly I knew it wasn’t bad,” she added. “In Canada, straight away it took my breath away because it hurt so much. I know I lay there for a while but I didn’t want to get up and make it worse.
“I just wanted the OK from Nige (doctor Nigel Jones). He slowly got me up and straight away I thought ‘It’s fine. I haven’t made it worse.’

“I’ve strained the muscle at the front here which means I can’t lift my arm above my head again. But it’s only muscles. They’ll fix after about a week. It isn’t bone. I haven’t made it any worse.”
Kenny fell hardest on her right hip, sparing the injured shoulder the full force of the blow.
The 27-year-old has already had a successful few days in Berlin. Determined to race here to show the Canada crash has not derailed her Olympic preparations, she picked up team pursuit silver on Thursday despite insisting last week she would not race in the event, then finished fourth in Wednesday’s scratch race.
