During a news conference, Houston Police Department Chief Art Acevedo said Detective Ray Cervantes was able to follow doctor's instructions.
The good news comes days after Ray's wife asked Houstonians to pray for her husband.
Det. Ray was in intensive care and on a ventilator for more than a week, according to Chief Acevedo.
Cervantes, with HPD for 27 years, most recently worked on the Homicide Cold Case Squad.
