Suge Knight -- Bail Reduction Denied ... Pleads Not Guilty

Suge Knight will not get the deep deep discount he wants on bail -- a judge denied his request during Knight's arraignment ... where he pled not guilty to murder.

The court previously reduced bail from $25 million to $10 million, but Suge wanted a judge to knock it down even more ... to $5 million. During Thursday morning's hearing ... the judge stood at $10 mil.

Suge walked on his own into court, but did use a wheelchair when he left. He previously complained he was embarrassed because deputies forced him to use the chair.
