RIO DE JANEIRO -- Brazil's President Jair Bolsonaro traveled on Sunday to Sao Paulo, where he is scheduled to undergo a reverse colostomy on Monday, official sources said.

Bolsonaro was stabbed in the torso during a campaign event in September, forcing him to undergo the surgery.

In Sao Paulo, he was admitted into the Albert Einstein Hospital for pre-surgical tests, according to a medical statement issued by the hospital.

Bolsonaro "underwent a pre-surgical clinical evaluation, (including) laboratory and imaging exams, with normal results," the hospital said.

According to presidential spokesperson Otavio Regos, Bolsonaro is expected be in recovery for a period of 10 days.

From the hospital, Bolsonaro posted a video on his social media account in which he thanked the show of support he has received.
