Alessandro Del Piero has promised to be fit in time for Juventus' first game after the winter break against Parma on January 6.
The talismanic striker has been missing ever since Juventus' 1-1 draw with Manchester City in the Europa League.
"I had an MRI yesterday which confirmed the outcome of my first visit to the doctor after a pain developed in the muscle of my right leg," Del Piero wrote on his official website.
"Luckily we are only dealing with a simple muscle fatigue. A few days rest will be enough for me to be back at the mister's disposition for our return on the pitch after the Christmas holidays on January 6 against Parma at the Olimpico.
"I am happy and relieved and I am only thinking about being in the best condition for the second half of the season.
"We end 2010 in a good position in the table and above all with every intention of still improving not just when we return on the pitch."
