Demetrious Johnson does not appear to be badly harmed after suffering his first career knockout loss at ONE on TNT I.

Johnson (30-4-1), a former longtime UFC flyweight champion, came up short in his bid for ONE Championship gold on Wednesday when got finished with strikes by Adriano Moraes (19-3) in the second round of their headlining bout at Singapore Indoor Stadium in Singapore.

“Mighty Mouse” got hurt with a big uppercut by Moraes, who proceeded to land a vicious knee on the ground that launched Johnson back into the cage. The Brazilian landed a few finishing blows to complete the monumental upset and become the first to put away the all-time great inside the distance.

It didn’t take long for Johnson to become alert after being put out. He conducted a post-fight interview on the broadcast, then when he returned to the fighter hotel, took to social media to provide an encouraging update on his condition (via Twitter):

all good everyone back in the hotel. watch the fight. shitty day in the office. congratz to @adrianomkmoraes we will be back.

Johnson said in his post-fight interview that, after the number of times in which he’s competed, getting stopped like he did was “bound to happen.”

He was in positive spirits, and made no indication that the results hindered his passion to push forward in his ONE Championship career.
