Kasper Fosser started in Sunday's World Cup sprint relay in Kolding, Denmark, where he won a Norwegian bronze medal behind the winner Sweden and second place Great Britain.

The idea was that Fosser would take revenge in tomorrow's knockout sprint, but now it is clear that the 23-year-old will be forced to give up.

The reason?

A groin that has been disturbing to and fro since last autumn.

- During yesterday's sprint relay, it felt really okay.

But I have consulted many of mine around me, both coaches and healthcare staff, and in the end we have ended up that it makes the most sense to stand over tomorrow's competition, says Fosser to orientering.no.

The Swedish team will start with eight runners.

In addition to Tove Alexandersson and Emil Svensk, who have free places as reigning world champions and European champions in sprint, Sara Hagström, Karolin Ohlsson, Lina Strand, Jonatan Gustafsson, August Mollén and Martin Regborn will also start.

Thus, it is clear that Isac von Krusenstierna, who last year took a surprising World Cup gold in sprint, will not start.

The knockout sprint has the same structure as the cross-country ski sprint with a prologue followed by the quarterfinals, semi and finals.

The 36 best from the prologue go on to the knockout round.

The competition will be broadcast on SVT Play starting at 4.30 pm tomorrow.
