The four-year-old daughter of boxing legend Mike Tyson was in "extremely critical condition" after she was injured in a treadmill accident at her home in Phoenix, Arizona, police said.

Exodus Tyson 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, according to police.

Former world heavyweight champion Tyson traveled from Las Vegas, Nevada, to Phoenix where his daughter was on life support in critical condition on Monday, police said. 

The family issued a statement through New York city public relations firm 42West.

"The Tyson family would like to extend our deepest and most heartfelt thanks for all your prayers and support, and we ask that we be allowed our privacy at this difficult time,"
