A call to Bryant's agent, Arn Tellem, was not immediately returned.
Bryant, 24, is charged with sexually assaulting a 19-year-old woman on June 30 at a mountain resort in Edwards, Colo. Bryant has said the two had consensual sex. His initial court appearance is tomorrow.
Yesterday, the judge in the case rejected Bryant's request to keep cameras out of the courtroom during his first court appearance.
Bryant's attorneys argued against allowing cameras during the hearing scheduled tomorrow, saying they could jeopardize Bryant's right to a fair trial.
Eagle County Judge Frederick Gannett ruled that was unlikely.
"Defendant's objections are general in nature and do not allege any specific prejudice which may result from expanded media coverage," the judge wrote.
