MEXICO CITY (AP) — Mexican icon Vicente Fernandez is in critical but stable condition after being hospitalized for a fall last week, according to an Instagram post made by his medical team on Wednesday.

While the 81-year-old king of ranchera music is on a ventilator, his brain function is intact, according to his doctors. They expect his mobility to improve and say he’s only minimally sedated.

The singer of such hits including “Volver, volver” and “Por tu maldito amor,” suffered a fall at his ranch in Los Tres Potrillos, outside of Guadalajara. The fall caused spinal cord trauma, according to reports.

Fernandez has had numerous health issues in recent years. He was hospitalized for a renal infection recently and in 2012, he underwent a complex surgery that removed almost half of his liver because of a tumor. A year after that he faced pulmonary thrombosis, and in March 2015, the singer had three hernias removed.

This year, Fernandez was faced with the release of photos that appeared to show him touching women without their consent while he was posing with them. He was also accused of sexual abuse by singer Lupita Castro. Fernandez has denied any inappropriate behavior.

Fernandez has sold more than 65 million albums and filmed more than 35 movies. He has won three Grammys and eight Latin Grammys, in addition to being named Person of the Year by the Latin Recording Academy in 2002.
