“My leg started giving out”: Former UFC Jarno Errens reveals shocking injury update

The problem became serious during training camp. An MRI later showed a large herniated disc and additional complications.

Jarno Errens thought the pain was normal at first

Errens explained that the issues started quietly during camp. Heavy sessions, soreness, fatigue. Nothing unusual for a fighter preparing for a bout.

That changed fast.

The Dutchman said the pain began shooting through his leg, followed by weakness and nerve symptoms that became impossible to ignore. At that point, his team decided further medical checks were necessary.

An MRI scan confirmed the damage. Doctors found a large herniated disc in his back, serious enough to require surgery.

Errens will undergo the procedure on May 26.

The announcement hit hard. You could hear it in his words.

“It honestly breaks my heart to have to share this news,” Errens wrote. “I was more than ready for this fight.”

The timing hurts. Especially after a full training camp.

The injury changed everything inside a few weeks

Back injuries can wreck a fight camp quickly, particularly when nerve pain starts affecting movement and strength. Errens described sharp radiating pain and weakness in one leg during preparation.

That is usually where training stops.

Fighters often try pushing through physical pain during camp, but nerve-related symptoms are different. Once strength disappears or shooting pain spreads through the leg, continuing becomes dangerous.

Errens and his team made the decision to step away and focus completely on recovery.

He did not sound defeated. Frustrated, yes. Angry even. But not finished.

“Setbacks are part of the journey,” he wrote. “I truly believe I’ll come back stronger from this.”

Fans who followed Errens during his UFC run know he rarely backed away from difficult fights or tough situations. This one happened outside the cage.

Now the focus shifts to surgery and recovery.
