MELBOURNE, Australia -- It's time for the eighth installment of the riveting, intergenerational rivalry between Novak Djokovic and Carlos Alcaraz. This one, though, will be the first at the Australian Open — and the first in the quarterfinals of a tournament; each of the others came in either a semifinal or final.

Novak Djokovic and Carlos Alcaraz will square off again in a Grand Slam after both stars won their fourth-round matches Sunday at the Australian Open.

Jack Draper withdrew from his fourth-round match with Carlos Alcaraz here at the Australian Open after suffering what looked like a recurrence of the hip trouble that had dogged him during the off-season.

Novak Djokovic will take on Carlos Alcaraz in a blockbuster quarter-final at the Australian Open on Tuesday. Alcaraz benefited from Jack Draper’s retirement after two sets of their clash before Djokovic defeated Czech Jiri Lehecka 6-3 6-4 7-6 (4).

Carlos Alcaraz reached his 10th career Grand Slam quarterfinal, tied for the most by a men's player before his 22nd birthday, by advancing at the Australian Open when 15th-seeded Jack Draper stopped playing because of injury after dropping the first two sets Sunday.
