Belgian cyclist Michael Goolaerts has died aged 23 after a crash in Paris-Roubaix.
The Veranda’s Willems-Crelan rider fell on the second set of cobbles in the one-day classic in northern France.
He suffered cardiac arrest and was airlifted to hospital in Lille but died at 21:40 BST on Sunday.
“It is with unimaginable sadness that we have to communicate the passing of our rider and friend Michael Goolaerts,” read a team statement.
The team said Goolaerts died “in the presence of his family members and loved ones, who we keep in our thoughts”.
The statement added: “For now there will be no further communication as we want to give his close ones time to deal with this terrible loss.”
Goolaerts crashed 109km into the 257km race and was found unconscious by race doctors. Television footage appeared to show him receiving CPR treatment from medics at the side of the road.
David Lappartient, president of cycling’s world governing body the UCI, said: “On behalf of the UCI and the cycling family as a whole, I would like to extend my deepest condolences to the family, team and loved ones of Michael Goolaerts, who left too early.
“We share their immense sadness.”
Goolaerts was in his fourth season with Belgian outfit Veranda’s Willems-Crelan in two spells.
He spent 2013 and 2014 with them at the continental level, and returned in 2017 after a season as a trainee with Belgian World Tour team Lotto-Soudal, where he won the opening stage of the 2016 Tour du Loir-et-Cher on the UCI Europe Tour.
Paris-Roubaix, which is known as the ‘Hell of the North’, is regarded as one of the toughest races in cycling, featuring 29 cobbled sections.
It is one of the five ‘monuments’, the most prestigious one-day races.
World champion Peter Sagan won the 2018 edition in a sprint finish with Silvan Dillier.
