Olympic champion Kayla Harrison has no plans to fight in the UFC just yet, but she hopes they were watching her win gold in the women's under 78kg judo.
The American defended her title at the Rio Games on Thursday, beating Frenchwoman Audrey Tcheumeo for gold.
Harrison, 26, said her judo legacy was "fulfilled" as she confirmed her plans to retire.
Despite reported UFC interest, Harrison said: "I've had offers from several different organisations but at this time I'm just going to enjoy being a two-time Olympic champion.
"I'm sure they were watching; if they weren't they missed out."
Harrison intends to turn her attentions to her charity - the Fearless Foundation - set up after she was sexually abused by a former coach.
"When I talk about changing the world, I'm talking about my Fearless Foundation; it is a foundation I founded after the London Olympics," She said.
"It's no secret that I was sexually abused by my first coach, and after the Olympics [in 2012] I decided to set up a foundation dedicated to the survivors of sexual abuse through education, through sport, a lot of different ways."
Harrison added: "Being a two-time Olympic champion is an amazing thing but the Fearless Foundation isn't about me; it is about helping people that need help.
"I want boys and girls all over the world to feel fearless."
