The shackles and blue prison garb seemed to weigh down O.J. Simpson as he returned to a Las Vegas courtroom on Monday to ask for a new trial in the armed robbery-kidnapping case that sent him to prison in 2008.

Looking grayer and heavier, the 65-year-old former football star and TV pitchman was flanked by guards as he nodded and raised his eyebrows to acknowledge people he recognized in the audience.

Simpson, now more than four years into a minimum nine-year prison term, will be in court all week to claim that he had poor legal representation in the trial involving the gunpoint robbery of two sports memorabilia dealers in 2007 in a Las Vegas hotel room.

Simpson's drab appearance contrasted with the fancy clothing he wore during his acquittal in his historic, high-profile 1995 murder trial in Los Angeles. The suit he wore then is now part of the Newseum collection in Washington, D.C.
