Conor McGregor left followers concerned after a cryptic late night voice message on social media.
McGregor shared the five second clip on Twitter in which he says: "I'm built like fucking steel."
And the clip was shared close to midnight Irish time.
And some followers were left concerned by the voice message.
One follower said: "12am in Dublin. What’s the craic?"
While another said: "What"
McGregor could be set for a return to the UFC in the near future.
The Dubliner has not fought since summer 2021 and suffered a horror leg break.
But there is optimism he might return in 2023 at welterweight.
