The former heavyweight champion had pleaded guilty in September to a single felony count of cocaine possession and a misdemeanor DUI count.

"I take responsibility for my actions," Tyson told Superior Court Judge Helene Abrams in an almost inaudible voice before she handed down the sentence.

Tyson, who will begin serving his jail time Tuesday morning, left the courthouse without speaking to reporters.

Tyson had faced a possible maximum sentence of four years and three months in prison. Prosecutor Shane Krausner had recommended one year in prison Monday, saying that Tyson was a multiple offender who previously had been convicted of a violent crime and that only now has he sought treatment for his drug addiction.

"Judge, by my calculations, this is his fourth or fifth chance," Krausner said.

The latest charges stemmed from a traffic stop in Scottsdale on Dec. 29 after the boxer had spent the evening at Scottsdale's Pussycat Lounge and was seen driving erratically. An officer said he saw Tyson wiping a white substance off the dashboard of his black BMW, and that his speech was slurred.
