Norwegian cross-country skier Therese Johaug tests positive

OSLO, Norway (AP) The Norwegian ski federation says three-time Olympic cross-country medalist Therese Johaug has tested positive for a banned substance contained in a sun screen.

The federation says she tested positive for the steroid clostebol in Italy in August.

The statement says the drug was contained in a sun lotion given to her by team doctor Fredrik Bendiksen.

Torbjorn Skogstad, the head of Norway's cross-country committee, calls it ''a serious situation'' and a meeting has been called to discuss ''any immediate measures.''

Johaug, a seven-time world champion, won gold in the 4×5-kilometer relay at the 2010 Vancouver Olympics. She took silver and bronze medals at the 2014 Games in Sochi.
