Welshman Geraint Thomas remains top of the Giro d'Italia after emerging unscathed from a crash that saw Briton Tao Geoghegan Hart taken to hospital after being "badly injured" during stage 11.
The Ineos Grenadiers rider, the 2020 champion, suffered the crash in wet conditions on a downhill descent with around 70km of the race's longest leg remaining.
Geoghegan Hart, who is third in the overall standings, was pictured being loaded into an ambulance after receiving roadside treatment.
His team said on Twitter: "We're gutted to see @taogeoghegan forced to abandon the £Giro following a crash on stage 11.
"The Brit will head to hospital for checks and we will have further updates in due course."
Team-mate and overall race leader Thomas was also involved in the multi-bike accident, but was able to continue along with Jumbo-Visma's Primoz Roglic.
Thomas said after the race: "As usual we were jostling for position, a UAE guy crashed next to me. I don't know exactly who was taken out after me.
"We were pretty much on the same spot. Unfortunately Tao is badly injured. It's obviously a big loss. He was going very well. He was in a really great position and it's very unfortunate to lose him this way."
Thomas retains the pink jersey for overall race leader with a two-second lead over Roglic.
Pascal Ackermann, riding for UAE Team Emirates, claimed the stage 11 victory after triumphing courtesy of a photo finish in Tortona, crossing the line just ahead of Jonathan Milan.
This year's race has been beset with problems as poor weather has been accompanied by a coronavirus outbreak, which has now seen 13 riders withdraw.
Soudal Quick-Step riders Jan Hirt, Josef Cerny, Louis Vervaeke and Mattia Cattaneo were the latest to pull out on Wednesday.
