There are indications that the N.B.A. is now considering new gambling restrictions for players. On Wednesday, the Nets informed players that gambling was no longer permitted on team flights.

?We did,? Rod Thorn, the Nets? president, said Thursday in a telephone interview in which he confirmed that the team had instituted a ban. ?I think after this incident with the Wizards that we just decided that we would not have any on our planes. We?ve never had a problem with it. But obviously, you can see what can happen.?

It is not clear whether any other teams are preparing to restrict gambling on team flights. A half-dozen team executives contacted on Thursday said they were not considering any new rules.

Donnie Walsh, the Knicks? president, said the Arenas case had caused him some concern over his own team?s gambling activity.
