Los Angeles, CA (CNN) - Former NFL star Darren Sharper pleaded not guilty in a Los Angeles court Thursday in the alleged drugging s and rapes of two women.
Judge Renee Korn raised Sharper's bail to $1 million from $200,000 in response to a prosecution request to raise it to as high as $10 million.
The judge also ordered Sharper not to frequent clubs, bars or any venue where alcohol is the primary item for sale. Sharper has already surrendered his passport, the judge noted.
"Mr. Sharper must stay in Los Angeles County," the judge said.
Sharper, who had been free on bail, stood quietly in a gray pinstripe suit with a black shirt and no tie.
One of his defense attorneys, Leonard Levine, told the court that Sharper was pleading not guilty, as well as denying all special allegations, enhancements and "priors," an apparent reference to alleged prior offenses.
The five-time Pro Bowl player, who became an NFL Network analyst, is charged with two counts of rape by use of drugs, four counts of furnishing a controlled substance and one count of possession of a controlled substance, all felonies, according to Los Angeles County prosecutors.
The alleged rapes occurred in October and last month, authorities said.
Sharper also is under investigation in Arizona, Louisiana and Nevada in connection with a total of five alleged rape cases in those states, according to Los Angeles authorities. Another of his attorneys, Blair Berk, has said she expects Sharper to "be fully exonerated."
