The international cycling federation informed the TdL organisers of their decision on Wednesday.
The 2020 edition became subject to strong criticism after the athletes' safety on the track was not guaranteed.
This means that according to UCI rules, the organisers of the Tour de Luxembourg will have to pay a monetary fine.
Nevertheless, this will not prevent the competition from being included in the 2021 calendar of the cycling ProSeries.
The competition will thus take place from 14 to 18 September.
