Chicago Blackhawks forward Patrick Kane has been ordered to appear in a Buffalo court on Monday to face felony and misdemeanor charges, the same day he is to report to the United States Olympic team’s orientation camp in suburban Chicago.

Kane, 20, and his cousin James M. Kane, 21, were arrested by the Buffalo police early Sunday morning after an altercation with Jan Radecki, a 62-year-old taxi driver. Kane, a Buffalo native, was the No. 1 overall pick in the 2007 N.H.L. draft and the winner of the Calder Memorial Trophy as rookie of the year for the 2007-8 season.

The Kanes pleaded not guilty Sunday to a felony count of second-degree robbery and misdemeanor counts of criminal mischief and theft of services.

According to statements by the police and by Radecki, the dispute began after Radecki picked up the Kanes in a downtown Buffalo nightclub district around 4 a.m. and prepared to drop them in a residential neighborhood near Canisius College. In an account in The Chicago Tribune, Radecki said that he did not have 20 cents in change for the $13.80 fare, and an argument ensued and the Kanes tried to take back the fare.
