Former heavyweight champion Mike Tyson has admitted to using a fake p-nis filled with his baby’s or wife’s urine to pass drugs tests during his boxing career.

Tyson revealed on his “Hotboxin'” podcast with the UFC’s Jeff Novitzky that he used a device called the “whizzinator” – a prosthetic p-nis attached to a urine bag – to avoid detection when he often took cocaine during the height of his career.

Tyson said, “It was awesome, man.

“I put my baby’s urine in it.

“One time I was using my wife’s [urine] and my wife was like: ‘Baby, you better not hope that it comes back pregnant or something.'”

Tyson admitted that he was afraid that the urine might come back pregnant, so he decided to use his child’s urine instead.

Novitsky, who oversees the UFC’s drug-testing program, told Tyson that his fears were well placed, saying, “A male [once] provided a urine sample and it came back and they said ‘Sir, you’re pregnant.

Either you’re pregnant or this is somebody else’s urine!” During the podcast, Tyson seemed to imply that he used the device numerous times, but a representative for the fighter told TMZ he only used it once.

Novitsky later asked Tyson if his “whizzinator” looked like his actual p-nis.

Tyson replied, “Hell yeah, I had a brown one.” Tyson’s use of the “whizzinator” raises questions about the effectiveness of drug testing in professional sports.

Tyson’s admission also comes ahead of his return to the ring for an exhibition match against Roy Jones Jr.

on November 28 in Los Angeles.

The event is being promoted by Triller, a social media app, and the fight is being marketed as the “Frontline Battle.” Tyson, who has not fought professionally in 15 years, has been posting training videos on his social media accounts, showing off his impressive speed and power.

Jones Jr., who is also a former world champion, has said that Tyson could still “cause a problem” in boxing’s heavyweight division because of his wild punching power.

However, some in the boxing community have expressed concerns about Tyson’s return to the ring at the age of 54.

Shakur Stevenson, one of the most exciting young talents in boxing, said that Tyson is “nuts” for getting back into the ring at his age.

Stevenson said, “I think Mike Tyson is crazy.

“I don’t know why he’s doing that.

“He’s a legend and he should be happy with what he’s done in the sport.”

Despite the concerns, Tyson has expressed his excitement about his return to the ring.

In an interview with ESPN, Tyson said, “I’m just ready to do this, man.

“I’m feeling really good, I’m excited. I’m ready to go.”

Tyson has also said that he plans to donate some of the money he earns from the fight to charity.

Tyson’s use of the “whizzinator” is not the first time that a professional athlete has used a prosthetic device to pass a drug test.

In 2005, Minnesota Vikings running back Onterrio Smith was caught at an airport with a device known as the “Original Whizzinator,” which he used to avoid detection during drug tests.
