There have been numerous Olympic gold-medal winners who have gone on to become world champions. In the heavyweight division alone there are hall of famers Muhammad Ali, George Foreman and Lennox Lewis and there are plenty more in the rest of the weight divisions.
However, this list features Olympic losers. These are 10 boxers who lost the gold-medal bout in their respective weight classes at the Olympics and went home with the silver instead. But they then went on to capture at least one world title after turning professional. Most of them would end up winning multiple belts and in some cases in more than one weight class.
10. Andriy Kotelnyk
Andriy Kotelnik of Ukraine fought as a lightweight at the 2000 Olympics in Sydney, Australia, and lost in the final match to Cuba’s Mario Kindelan. Kotelnik won four fights leading to the gold-medal showdown, two by decision and two by stoppage. He took home the silver after losing 14-4 in points to Kindlan. Kotelnyk turned pro later the same year and would go on to win the WBA Super Lightweight Title in 2008 with a 12th-round TKO over Gavin Rees. He defended it against Norio Kimura and Marcos Maidana, but then lost the belt to Amir Khan of England by unanimous decision 16 months after winning it. Kotelnyk then fought Devon Alexander for a pair of junior welterweight titles in 2010, but also lost by unanimous decision. He fought once more in 2014 after a four-year break, won the bout and retired with a record of 32-4-1 with 13 Kos.https://static.guim.co.uk/sys-images/Sport/Pix/pictures/2009/7/14/1247590199291/Andreas-Kotelnik-boxer-001.jpg Source: alchetron.com
