Arnold Schwarzenegger has reassured fans that there's "nothing to worry about" after he was drop-kicked during a sporting event in South Africa.
It happened at the Arnold Classic Africa event in Johannesburg.
Video footage shows a man running at the actor and politician before kicking him in the back.
Schwarzenegger stumbled forward slightly after being kicked, but otherwise appeared largely unfazed by the surprise kicking.
Posting on Twitter, Schwarzenegger said: "Thanks for your concerns, but there is nothing to worry about.
"I thought I was just jostled by the crowd, which happens a lot. I only realised I was kicked when I saw the video like all of you."
The Austrian-American star posted a video of the incident himself - but also encouraged fans to instead put the spotlight at the athletes attending the event.
And if you have to share the video (I get it), pick a blurry one without whatever he was yelling so he doesn’t get the spotlight.
By the way... block or charge? pic.twitter.com/TEmFRCZPEA

In a statement, organisers said: "Sandton Convention Centre security responded swiftly by apprehending the offender and handing him over to police."
Mr Schwarzenegger is also reported to have said he won't be pressing charges.
Meanwhile, Wayne Price - organiser of the event - said Schwarzenegger was fine and in good spirits.
In comments quoted by Sky News, he added: "He still carried on with the activities as planned and is fully taking this in his stride.
"He even joked that some people got more excited than others."
