David Stern Says Leave Your Air Punches At Home, Thank You Very Much

JERSEY CITY, N.J. -- At the referees' annual meeting, the NBA announced the guidelines for technical fouls will expand to include "overt" player reactions to referee calls.

Referees have been instructed to call a technical for:

• Players making aggressive gestures, such as air punches, anywhere on the court.

• Demonstrative disagreement, such as when a player incredulously raises his hands, or smacks his own arm to demonstrate how he was fouled.

• Running directly at an official to complain about a call.

• Excessive inquiries about a call, even in a civilized tone.
