(CNN) Robert Kraft entered a plea of not guilty to two misdemeanor counts of soliciting prostitution and requested a jury trial, according to court documents filed Tuesday in Florida.

Kraft, billionaire owner of the New England Patriots, waived his right to an arraignment.

He is scheduled to be in a West Palm Beach courtroom the morning of April 9. The notice says the defendant must be present at the hearing.

Kraft, 77, was charged with soliciting prostitution last month in Palm Beach County.

Kraft has denied that he committed a crime.
