Thiago Santos underwent a four-hour surgery on both knees days after challenging Jon Jones for the UFC light heavyweight title, and his long road to recovery is not an easy one.

“Marreta” is currently in Las Vegas for his physical therapy at the UFC Performance Institute, and shared a video Wednesday night on social media showing how his days have been like.

“It’s been 7 days since the surgeries on my knees,” Santos wrote. “I must admit, these days are tough, filled with a lot of pain. I can’t sleep or eat properly due to the medications. I even fear using the bathroom because the walk there is a battle. Thank God the pain is subsiding.”

Santos (21-7) was riding a four-fight winning streak prior to his close decision loss to Jones at UFC 239, including a win over Kevin Holland at middleweight and a trio of stoppages in 205-pound bouts with Eryk Anders, Jimi Manuwa and Jan Blachowicz. He’s expected to be cleared to fight again in mid-2020.
