The Spaniard opted not to play his second match at an exhibition event in Abu Dhabi last week after tweaking his thigh and is anxious about the risk of exacerbating the problem.
"I tried to play and I still wanted to play but the two doctors from here and the doctors from my confederation in Spain tell me. if I play here, there is a risk (I won't) have the chance to play Melbourne", Nadal said.
"I want to feel myself competitive every day that I am on court and I want to keep fighting for the things that really make me feel alive, for the things that motivate me".
"I did an MRI and it shows a small scaring on my left thigh".
Nadal won the Australian Open in 2009 and would dearly love to add another title on the hardcourts of Melbourne. "I can't do my 100 percent".

Forced to withdraw from 18 of his past 19 tournaments on hard courts since 2017, the 32-year-old's only recent hit out came last month at the Mubadala Championship in Abu Dhabi where he made the semifinals.
"My goal is just to be happy doing what I am doing and be competitive all the weeks that I am playing. I feel myself ready and always it's tough when you have to go from a tournament, but especially if you feel yourself ready and playing well, and that was the case".
