It was during Saturday's 15 kilometer race in Gällivare that Jens Burman was forced to break due to back pain.
He was examined yesterday and will be examined further today.
- He met medical staff yesterday at home and we continue today.
So today he meets the physiotherapist again, I will get reports and then we will see how we proceed.
But right now there are no major changes, says the cross-country national team doctor Jan Wall to SVT Sport.
What has the survey shown so far?
- I can not say more than that it is a muscle that cramps and that in itself is not so dangerous, but when you have the history that he has, you want to get to the bottom of it so that you know what you are talking about.
Although Burman, who has previously suffered from back problems, can train, he will not compete in this weekend's world cup premiere in Ruka.
There is a risk that he will also miss the competitions in Lillehammer the weekend after.
- You have to take it day by day with Jens.
We follow a process, how it has been and how it passes.
If it gets worse, you have to think again.
So it is important to start broadly and then work downwards to find the core of the problem, says Wall.
When do you think you know more about his status?
- You can probably let this week go.
I will of course get reports on what happens but a back is a bit like a puzzle and there are many pieces to be added considering his history.
