The 21-year-old star canceled last week's Tour de Ski after six of eight stages after she was injured in a hotel room between stages 4 and 5.
Karlsson is back in training after giving up Saturday's sprint and Sunday's climb in Val di Fiemme, Italy, but will not travel with the national team at upcoming World Cup competitions.
"It feels good anyway.
This week there will be some focus on rehab but I can basically train as usual.
To be completely on the safe side and not stress anything, I will stand over Lahti to be one hundred percent ready for a fight at home in Falun the following weekend ", says Frida Karlsson in a press release.
The competitions in Lahti are arranged on January 23-24 with skiathlon and relays.
