Gary Washburn of the Boston Globe reports:

A Celtics minority owner could face a fine by the NBA after a verbal confrontation with commissioner David Stern following the Celtics’ 91-84 Game 3 loss to the Lakers Tuesday night at TD Garden.

According to multiple sources with knowledge of the encounter, Jim Pallotta, angry at the officiating that included three reviewed calls in the fourth quarter, confronted Stern and apparently said the league should be embarrassed at the officiating in the series.

Historically, owners who have been publicly critical of officials have received six-figure fines.

Stern told reporters at an NBA Cares event in Roxbury yesterday that it wouldn’t be Celtics-Lakers without complaints about the officiating. The NBA officially had no comment on the incident, while a Celtics spokesman said he was unaware of it.
