Today doctors told UFC welterweight fighter Thiago Alves, he should be able to back in the gym in just three weeks.

Alves’ trainer, Ricardo Liborio, reported that Thiago underwent successful brain surgery today in New York City, to correct an arteriovenous fistula, which is defined as ‘an abnormal connection or passageway between an artery and a vein’, on the left side of his brain.

The procedure took place at Roosevelt Hospital Center by Alejandro Berenstein, a very well-known neurointerventionalist. “Everything is good,” Liborio reported.

Alves was supposed to have a rematch this past Saturday against Jon Fitch, but was pulled out two days before when a pre-fight exam discovered a brain abnormality. Ben Saunders then went on to pull out of his scheduled fight with Jake Ellenberger to take Alves’ place.

At first glance, many were worried about Alves’ future in the MMA world, but luckily an exam with Berenstein a day after the suspension showed that the abnormality would not end Thiago’s career.

Alves will only have to stay in the hospital one night if all goes well. Liborio says doctors expect a healthy, full recovery.

“The first thing he said when he got out of anesthesia was, ‘When can I get back to training?'” Liborio said. “In three weeks, he should be training if he doesn’t do anything stupid.”

This fight at UFC 111 was the second time Alves was scheduled to have a rematch with Fitch. He was supposed to fight him at UFC 107, but a knee injury forced him out of that fight as well. Alves and his camp have requested for him to fight at UFC 114 on May 29th.

“It’s the second time the fight was supposed to happen, and it didn’t,” Alves said. “I just have this bloody taste in my mouth, and I have to get it out. I guess it just wasn’t the right time.”
