RM hurt his ankle/foot , not something more dramatic happening to his whole leg, and it was an accident during dance rehearsal for BTS’s big “ARIRANG” comeback stages in March 2026.

What Happened to RM’s Leg?

(Quick Scoop on the Injury)

The Actual Injury

Multiple official statements from BigHit Music and news outlets say that RM injured his ankle during a performance rehearsal on March 19, 2026, ahead of BTS’s comeback shows.

Doctors diagnosed him with:

  • A sprain of the accessory navicular (an extra bone in the foot some people have)
  • A partial ligament tear around the area
  • A talus contusion (a bone bruise in the ankle joint area, with ligament damage/inflammation)

He was advised to:

  • Wear a cast/boot on the injured leg
  • Limit movement strictly (especially dancing) for at least two weeks to focus on recovery

So when people ask “what happened to RM’s leg,” they’re basically talking about this rehearsal accident and resulting ankle/foot injuries.

How It Affects Performances

BigHit made it clear that RM would still join the comeback events , but his stage participation would be partially limited.

  • He was expected to avoid intense choreography or “violent” dance moves , standing or sitting and focusing more on singing, rapping, and talking to ARMY instead.
  • At the time of the announcements, the plan was to minimize movement but not completely remove him from the show.

RM himself appeared with a boot on his left leg, saying he wouldn’t be able to “perform right away” but would still be on stage to sing and hype up the audience.

What RM Said About It

In a livestream and comments reported by entertainment outlets, RM called the situation “sad” but tried to reassure fans.

He shared that:

  • He had been pushing himself very hard in rehearsal for this comeback.
  • On the day of the injury, he was especially fired up and ended up hurting his ankle while practicing.
  • He promised to follow medical advice and take care of it , telling fans not to worry too much.

Members also mentioned they were shocked when it happened and initially thought he was joking, since he’d had ankle sprains before but usually carried on.

Forum & Fan Discussion Vibes

On forums like Reddit and in fan spaces, the mood is a mix of worry and “please just let him rest.”

Common sentiments:

  • Concern because a partial ligament tear is serious and could affect schedules and travel.
  • Frustration on his behalf, since this is one of BTS’s most symbolic comeback stages and he was so eager after military service.
  • General agreement that prioritizing his long‑term health over one performance is the right call.

You’ll also see people sharing the photo of his ankle wrapped with a thick bandage/cast that he posted with a crying emoji, which fueled a lot of “what happened to RM’s leg” posts.

Is It Permanent or Super Serious?

From what’s publicly reported so far, this is a significant but treatable ankle/foot injury.

Key points:

  • Accessory navicular issues and talus contusions can be painful, but with rest and proper care, people often recover well.
  • Doctors specifically recommended a limited movement period of at least two weeks , implying they expect improvement with conservative treatment.

There’s no official indication of permanent damage at this time; everything released publicly frames it as an injury that needs short‑term protection and rehab.

Mini FAQ

Q: Did he break his leg?
No. The diagnosis mentions a sprain, partial ligament tear, and bone contusion, not a fracture.

Q: Why is he still performing at all?
Because this comeback stage at Gwanghwamun is very symbolic, and RM strongly wanted to be there, so the compromise is limited movement , not full absence.

Q: Should fans be really worried?
It’s a serious sprain plus ligament damage, so concern is natural, but both the agency and RM emphasize rest, a cast/boot, and following medical advice for recovery.
