Peter Sagan will miss Tokyo 2020 after undergoing surgery on a knee injury suffered during the Tour de France.
The three-time world champion has been replaced in the Slovakian squad for the Olympic men’s road race by Lukáš Kubiš.
Bora-Hansgrohe confirmed yesterday that Sagan had undergone what they described as a “small surgery” near his home in Monaco.

“We did everything possible on site at the Tour but even antibiotic treatment couldn’t prevent an infection,” said the team’s Head of Medical, Christopher Edler.
“The only option was to stop racing and get the bursa surgically removed. The surgery went well. Luckily it was only a superficial infection, and the knee joint is not involved in this at all.”
Sagan had been due to ride the road race alongside older brother Juraj.
Winner of the green jersey on seven occasions, Sagan endured a disappointing Tour de France by his standards after being involved in a high-speed crash with Caleb Ewan on Stage Three into Pontivy.

This will be the second consecutive Olympic road race that Sagan, one of the most decorated riders of his generation, will miss, having pulled out in 2016 to instead compete in mountain biking.
Describing the incident that ended his Tour, Sagan said: “The chainring hit my knee and entered the skin above the patella, leaving a deep wound.
“We cleaned the wound as much as possible to prevent infection because of the dirt from the chain oil. However, after a few days, an inflammation developed in the bursa on top of the patella, and, unfortunately, I had to abandon the Tour.”
Sagan finished 34th in the road race at London 2012.
He has been the subject of intense speculation over his future, with TotalEnergies rumoured to be close to securing his signing on a three-year deal from 2022.
The deal would also see bike manufacturers Specialized come onboard with the French team, along with Sagan’s familiar cabal of recurring teammates, including Daniel Oss and Maciej Bodnar.
Juraj Sagan is also expected to follow his brother to TotalEnergies.
The elder Sagan will now team up with highly-rated 21-year-old Kubiš, who has finished third at each of the last two editions of the Slovakian National Road Championships.
He currently rides for Dukla Banská Bystrica, the Slovakian Continental team where both Sagans began their careers.
The men's road race is scheduled for 24 July on a course that will finish at the Fuji Speedway circuit.
Vincenzo Nibali became the latest big-name rider to withdraw from the remainder of the Tour de France in order to prepare for a tilt at a gold medal.
The Italian confirmed his long-planned departure from the three-week race on Monday’s second rest day, describing it as “perfect” preparation for the Olympics, where he will compete alongside Trek-Segafredo team-mate Giulio Ciccone
“I raced a different Tour compared to my past experience, but similar to 2016 before Rio,” said Nibali. “The Tour is a boost for everyone; you can compare with the top [riders] in the world. I think it was the perfect way for me to reach the top form for Tokyo.
The feeling is good, but for a race like the Olympics you need the entire team at the top.
"I’m sure my team-mate [Giulio] Ciccone will be a key rider for the team.”
Nibali crashed on the final descent in Rio in 2016 and failed to finish the race, eventually won by Greg van Avermaet.
Damiano Caruso, Alberto Bettiol and Gianni Moscon are the other three members of a strong Italian team named for Tokyo 2020.
