Novak Djokovic and Carlos Alcaraz are set to meet for the Wimbledon men's championship.
Sunday's final at the All England Club is a rematch from last year, when Alcaraz got past Djokovic in five sets.
Kate, the Princess of Wales, is expected to be in the Royal Box at Centre Court, a rare public appearance after her cancer diagnosis.
The 37-year-old Djokovic is trying to win his eighth Wimbledon title to equal Roger Federer for the most by a man at the grass-court major. A victory by Djokovic would also give him 25 Grand Slam singles titles, more than any other player in tennis history.
It was only a little more than a month ago that Djokovic had surgery for a torn meniscus in his right knee after getting injured during the French Open.
The 21-year-old Alcaraz wound up winning the trophy at Roland Garros in June for his third major championship. That made him the youngest man with a Grand Slam title on grass, clay and hard courts.
