Nadal has a "micro tear" in a muscle, which is a different injury from the one that kept him out for a significant period previously.
After feeling concerned during his last match in Brisbane, Nadal underwent an MRI in Melbourne, which confirmed the muscle tear.
Nadal has stated that he is currently not prepared to compete at the highest level required for five-set matches, a standard format in major tennis tournaments like the Australian Open.
Nadal plans to fly back to Spain to consult with his doctor, seek treatment, and rest, indicating a focus on recovery and future play.
Despite the setback, Nadal maintains a positive outlook. He has expressed that while he's sad about not playing in Melbourne, the injury isn't overly severe and he remains hopeful about his season's progression.
Nadal has worked hard for his comeback and aims to be at his best level within three months, a goal he has mentioned previously.
Before this injury, Nadal played a few matches in Australia, which he found to be a positive experience and a source of happiness.
Nadal has won the Australian Open twice, first in 2009 and then in 2022, showcasing his long-standing success in the tournament.
