Rockville (USA), Feb 21: Former heavyweight boxing champion Mike Tyson will face disciplinary action in a Maryland jail tomorrow after a violent temper tantrum that could make it harder for him to gain an early release to resume his career.The volatile 32-year-old fighter, who was jailed on February 5 for assaulting two older motorists after a minor traffic accident, had to spend the weekend in isolation after hurling a television against a set of bars at the Montgomery County detention centre.Authorities had only sketchy details of the incident but said a closed-door disciplinary hearing was set for tomorrow.``Tyson was going through some problems on Friday night,'' Eric Seleznow, spokesman for the Montgomery County Department of Correction and Rehabilitation, said Saturday.``He threw a TV. He was written up and remanded to the facility's administrative segregation area. He threw it against some bars with people on the other side. No one was injured.''Tyson has been in the Montgomery Countyjail for two weeks. A judge sentenced him to 12 months imprisonment for punching a 60-year-old man in the jaw and kicking a 50-year-old in the groin last August after a traffic accident. County officials said he has been housed with about a dozen other inmates who are secluded from the 640 other prisoners. Tyson, a convicted rapist was suspended from boxing for over a year for biting the ears of world champion Evander Holyfield.
