The Brazilian MMA veteran suffered a fracture in his skull during a welterweight clash with Michael Page at Bellator 158 on July 16, and underwent surgery 11 days later in Houston, Texas, to fix the injury.
"I had surgery yesterday, and thank God everything went fine," Santos told MMA Fighting on Thursday. "It lasted seven hours, and the hospital will give Bellator a full report later today. God guided the doctors in this surgery so everything went well."
Prior to the surgery, Santos (21-18) told MMA Fighting that he was planning on fighting 10 more times before retiring.
