Prior to stage 19 getting underway, Enric Mas (Movistar) was the latest rider to leave the Tour de France due to Covid. This means just 139 riders are due to start Saturday's penultimate stage.
On Thursday, Chris Froome (Israel-Premier Tech) was forced to abandon due to a positive test for Covid.
Elsewhere Marc Soler and Rafal Majka (UAE Team Emirates) were forced to abandon this week due to illness and injury leaving just three team mates for Tadej Pogacar.
Damiano Caruso (Bahrain Victorious) also tested positive for Covid-19 before stage 18 meaning he would not start the stage.
AG2R Citroën riders are left with just three riders for the remainder of the Tour, having already lost Aurélien Paret-Peintre, Mikaël Cherel, Oliver Naesen, Ben O'Connor and Geoffrey Bouchard.
High-profile withdrawals include Primož Roglič (Jumbo-Visma) and Mathieu van der Poel (Alpecin-Deceuninck), the former leaving the Tour before stage 15 after struggling with a back injury he picked up on stage five. Van der Poel, meanwhile, cited fatigue as his reason for withdrawal.
As a result, only five of the 22 teams have a full compliment of riders, with injuries, positive Covid results, fatigue and illness all causing early retirements.
Last year, 42 riders didn't manage to finish the Tour de France, with the Olympics playing a major role in those withdrawals. With six stages still remaining, there's potential for plenty more dropouts - which Cycling Weekly will keep updated stage-by-stage.
