The most successful female Olympian of Great Britain broke a shoulder as she crashed at a World Cup event in Canada last month.
Kenny, 27, avoided surgery so she might be selected for the omnium in Berlin next week, but she is going to sit out the team pursuit and therefore the madison.
And that has put her on the rear foot before the Games in July, where she hopes to require her gold tally to seven — quite any Briton has won.
Kenny won gold within the team pursuit and individual omnium at London 2012 and Rio 2016. Tokyo are going to be the primary time the two-person madison has been a part of the women’s track cycling schedule for the Olympics and Kenny is one among four Great Britain girls competing for an area .
While Kenny remains likely to be selected within the team pursuit for Tokyo if fit, her chances of competing within the madison now look slim, especially if Barker and Evans perform well in Berlin.
In the men’s team, the rising star Ethan Hayter of Great Britain has also been dealt a blow in his bid to ride all three events at the Olympics.
He has been selected for the team pursuit at the planet Championships, which can be spearheaded by veteran three-time Olympic champion Ed Clancy, also because the madison with Ollie Wood.
But Hayter has been overlooked for the omnium in favour of Matt Walls despite winning bronze within the event eventually year’s World Championships in Poland.
British Cycling selectors don’t need to decide which riders will race during which events until they’re actually call at Tokyo.
But cyclists view the choice for the planet Championship as a serious indicator into their chances of being picked for events at the Games.
