Belgian Kris Boeckmans remains in an induced coma following a crash at the Vuelta a Espana on 30 August, but is no longer relying on a machine to breathe.
The Lotto-Soudal rider, 28, suffered concussion in the accident on the eighth stage, 50km from the finish.
Boeckmans, who is still in intensive care, suffered no brain injuries but did have facial and rib fractures.
Lotto-Soudal team doctor Servaas Binge is hopeful his condition will improve "day by day".
"In the next few days [we] will see when the induced coma can be diminished," he said.
The accident caused five riders to pull out of the race.
After a rest day on Tuesday, the Vuelta resumes on Wednesday with Spain's Joaquim Rodriguez holding the race leader's red jersey.
