Today, the American national athletics team presented its squad for the home World Cup in Oregon, which begins next week.

Then pole vault star Sam Kendricks was not present.

It is because he has not recovered well enough from his meniscus surgery that he did on May 2 this year.

- We thought that the recovery would go much faster, but he has had a couple of setbacks.

Sam did not feel he was in a position where he could fight for the medals, says his agent according to NBC Sports.

Kendricks did not participate in the American championships, which also serve as World Cup competitions, but he had still got a place thanks to the fact that he is the reigning world champion.

The American competed no later than April 8 and also intended to participate in the Diamond League competition in Oslo, but withdrew at the last minute.
