When SVT Sport reaches Johanna Mattsson over the phone, the news has just been published. For obvious reasons, Mattsson has not been able to take part in the news coverage himself, but is shocked.

- I hope and think it's a mistake. I have known Jenny since we were little and I know she takes great distance from doping, she says.

Johanna Mattsson and Jenny Fransson both belong to the "wrestling wonder from Gällivare", the club in Norrbotten county that has reaped great success especially on the ladies side.

Today both Jenny and Johanna train and live in Helsingborg.

According to Dagens Nyheter, which was first with the news, it is a very small amount of the illicit substance methyltestosterone, an anabolic steroid. According to her own statement, Jenny Fransson must have received the preparation by mistake.
