"Jabeur/Williams withdrew from their semi-final due to Ons Jabeur's right knee injury," the English Tennis Association wrote on its Twitter account.
The American-Tunisian pair were to face Polish Magda Linette and Serbian Aleksandra Krunic for a place in the final.
During the first round on Tuesday, the Tunisian had slipped on a support, her legs giving way under her and, during the quarter-final disputed on Wednesday, she had repeatedly held her right knee by turning it, obviously embarrassed.
Engaged in this tournament to prepare to play Wimbledon, which she won seven times, Williams had crossed, at 40 and after a blank year, the first two rounds with the world N.3 in singles.
They had first dismissed with difficulty in three sets the Czech Maria Bouzkova and the Spaniard Sara Sorribes Tormo, before a more convincing victory in two sets against the Japanese Shuko Aoyama and the Taiwanese Chan Hao-ching.
At Wimbledon, Williams will line up in singles thanks to a wild card awarded by the organizers.
"I feel good. I feel as good as possible after going so long without playing," she commented on Wednesday evening after her match.
"I told Ons after the game that it was a really good game and the second set especially, they played really well and we were able to play differently depending on the circumstances," she added.
"It's exactly what I needed and what I wanted to do by coming here, I couldn't ask for more," said the player with 23 Grand Slam titles.
At Wimbledon, Williams will not be seeded and will know Friday, during the draw, his opponent in the first round.
