The 4-year-old daughter of boxing legend Mike Tyson was in "extremely critical condition" Monday night after she was injured in a treadmill accident at the family's Phoenix, Arizona, police said, CNN reported.
The girl was found by her 7-year-old brother on a treadmill "with her neck on ... a cable" attached to the machine, police said in a statement.
The mother "took her daughter off the cable," and called authorities.
The girl remained on life support in critical condition on Monday, police said.
