BRIEFLY : COWBOYS OWNER ANGRY AT SWITZER.

Barry Switzer has the support of his players, but not necessarily his boss. Dallas Cowboys owner Jerry Jones talked to the NFL about an appropriate punishment for the coach, who was arrested for carrying a loaded, unlicensed gun through an airport, a source told The Associated Press on Tuesday. One option would be a fine, according to the source, who spoke on condition of anonymity.

Jones has said he wouldn't stand for the kind of behavior that led to the suspensions of five players, including Michael Irvin and Leon Lett. ``I really feel even stronger than I've ever felt that we've got to look at even how a mistake is perceived and how it does reflect on what we're about,'' he said. He said a mistake by someone in an influential position is ``an even more serious matter than it would be if it were a player.''

According to league policy, all league employees are prohibited from carrying firearms while conducting NFL business.

Baltimore Ravens running back Bam Morris is expected to be suspended for the first four games of the NFL season following his second violation of the league's substance-abuse policy, according to broadcast reports.

WBFF-TV and WBAL, both in Baltimore, and Fox Sports News all quoted unidentified sources as saying Morris told teammates he had failed a mandatory drug test several months ago, but only learned that he had lost his appeal this week.

University of Minnesota basketball player Courtney James was found guilty of one count of domestic assault and was cleared of a second similar charge.

YACHTING: The United States kept its lead in the Admiral's Cup yacht race despite losing a man overboard on one of the in-shore races. David Navin, bowman on the big boat ``Flash Gordon 3'', fell over the side during the first of two races. The crew on Jim Brady and Ken Read's yacht was forced into a dramatic rescue as it dragged Navin from the water, losing vital time on the final heat of the race and finishing last in their class. Navin was unhurt and completed the second of two races.
