Rafael Nadal will miss the Australian Open and instead return to Spain for treatment on a hip injury he sustained at the Brisbane International.

Nadal, 37, made his long-awaited return after almost a year out with injury this week, winning his first two matches in Brisbane in straight sets.

But he was injured in his quarter-final loss to Jordan Thompson on Friday.

Nadal said a scan had shown a micro tear on a muscle but not in the same area as his previous long-term injury.
