Andy Murray will attempt to secure a place in the second week of Wimbledon in his quest for a second title.
The British number one faces Australian John Millman on Centre Court after the conclusion of Romanian Simona Halep's match against Kiki Bertens from the Netherlands.
World number two Murray is the only Briton remaining in the singles draw.
Novak Djokovic will resume his match against Sam Querry on Court One, after rain saw their match called off when the Serbian was two sets down to the American on Friday.
The bad weather that has disrupted play throughout the week led the All England Club to announce there would be play at the championships on Sunday - the first time since 2004 and since the roof was introduced on Centre Court.
More details of the Sunday schedule will be issued later on Saturday, but the club has already said that tickets would be sold online on a first-come, first-serve basis, with none being sold on the day.
It is only the fourth time in the club's 139-year history that the middle Sunday - traditionally a rest day - will see play.
