Jailed former heavyweight boxing champion Mike Tyson faces a disciplinary hearing in Maryland today after hurling a television set into a set of metal bars.

The outburst could prompt prison officials to place tighter restrictions on Tyson, who with good behaviour might be able to resume fight training in May and box through a work-release programme.

No one was injured in Tyson's angry outburst, which came Friday night at the Montgomery County Detention Centre, where he spent Saturday in isolation.

Tyson, 32, has been kept with about 12 other prisons in a special section of the jail secluded from the main population of 640 prisoners since he received a one-year jail sentence February 5th.

Tyson pleaded no contest to assault charges stemming from an August 31st car accident in which he punched an elderly man and kicked another after their vehicle rear-ended one being driven by Tyson's wife Monica.

Attorneys for Tyson have two weeks to file an appeal of the sentence and seek a trial on the charges if they desire.

Meanwhile, Panamanian boxing legend Roberto Duran's bout with Argentina's Omar Gonzalez was cancelled in Argentina yesterday because the former multiple world champion weighed in six kilograms overweight.
