Anthony Joshua’s injury history: Health setbacks that tested the heavyweight champion

Anthony Joshua’s career looks shiny from the outside. Big wins. Big stages. Big moments. But the truth is, his journey hasn’t been smooth at all. Behind the belts and headlines is a body that’s taken serious punishment over the years, and a fighter who’s had to learn the hard way that strength alone isn’t enough.

What makes AJ different from a lot of fighters is how honest he’s been about it. He’s never sold the idea that he’s made of steel. If anything, he’s shown that listening to your body is part of surviving at the top.




In his early pro years, Joshua was all about power and intensity. Training camps were brutal. Long sparring sessions, heavy lifting, explosive drills, day after day. And his body felt it. He’s mentioned dealing with back stiffness and muscle issues early on. Nothing dramatic, nothing that stopped fights, but enough to send signals.

Those little aches mattered. Heavyweights don’t just throw punches, they absorb them. AJ’s size and athletic build put extra stress on his joints and muscles, and at that stage, he was still figuring out how much his body could actually handle.

The knee problems

One of the more quiet issues Joshua has dealt with is his knees. It’s not the kind of injury fans talk about much, but for a heavyweight, it can be huge. Balance, footwork, power generation, it all starts from the legs.

Joshua has admitted that knee discomfort affected certain camps. Sometimes it meant changing training completely. Less impact work. Fewer explosive movements. More recovery. That wasn’t an easy adjustment for someone raised on the idea that pushing through pain proves toughness.

But he changed. Ice baths, physio, mobility sessions, proper rest. Stuff that used to feel optional became essential. It marked a shift from trying to outwork pain to actually respecting it.

Head trauma, concussion

Then there’s the part no boxer can escape. Head trauma. After tough fights, especially the loss to Andy Ruiz Jr. and the back-to-back defeats against Oleksandr Usyk, people started asking questions. Not just about tactics, but about Joshua’s health.

AJ hasn’t publicly talked about diagnosed concussions, but he has acknowledged the mental fog and exhaustion that can follow intense fights. He’s spoken about medical checks, taking time off, and allowing his body and mind to recover properly.

In boxing, that kind of honesty isn’t common. Fighters are expected to shrug things off. Joshua didn’t. And that mattered.

The mental toll injuries

Physical injuries are one thing. The mental side can be worse.

Joshua has been open about how injuries and losses messed with his confidence. Being sidelined. Feeling your body isn’t reliable anymore. Reading criticism everywhere you turn. It adds up fast.

After his recent losses, he admitted he felt emotionally drained. Injuries stripped away the one thing fighters rely on most, trust in their own body. That forced him to rethink everything, from training to mindset.

He started focusing more on balance. Not just boxing every day, but life outside it. Mental resilience became just as important as physical conditioning.

Life-threatening car accident

Anthony Joshua recently made headlines after reports emerged of his involvement in a car accident in Nigeria on the busy Lagos–Ibadan Expressway. According to early accounts, the crash was serious and claimed the lives of at least two other people. AJ was rushed to a nearby hospital for treatment, where doctors confirmed his injuries were non-life-threatening. He was said to be shaken but stable, and later updates suggested he was recovering well. The news shocked fans worldwide, who flooded social media with messages of concern and prayers.
