The BMC star cut his season short in early September after suffering during the USA Pro Cycling Challenge in Colorado, after which it transpired he had been suffering from a virus.
He is planning to return to training in the coming weeks, but only once he is given the all-clear by specialists in Milan.
"Based on (the tests), we will decide the management of his condition," BMC’s head medic, Dr. Max Testa, said in a team statement.
"The plan is still to maintain the winter training schedule that was discussed before. So there's no reason to think we will change his training program at all for next season."
The Australian looked under the weather when he failed to defend his Tour de France title in June.
While he managed to complete the Olympic road race in late July, the 35-year-old withdrew from the subsequent time trial before pulling out of the US event and then the Road World Championships in Limburg in September.
When his problem was finally diagnosed, it came as a relief to Evans who, as a new father, is enjoying the break from the UCI Pro Tour.
"Once we had a good idea of what was affecting me, I didn't want to compromise my 2013 by racing longer," Evans said.
"So it's been nice to take a good rest and completely recover from this virus and work toward being back to my normal level next year.
“Being a first-year dad, I've also enjoyed the free time with my family."
