Willliam Poromaa was five seconds behind the lead when it was time for a change of skis.

Then he quickly lost time.

It turned out that he dropped the ski in the track and was close to felling Burman.

- Then the change went a little too fast, says SVT Sports expert Anders Blomquist.

By the time after the ski change, he had lost nine places and was 19 seconds behind.

Marcus Grate coaches his teammates along the track and gave a report on the situation.

- He can not really have put it on when changing skis, very unfortunate.

It will be a few seconds up now, he says.
