Bynum was whistled for two consecutive technical fouls in the fourth quarter of the Lakers' 109-87 win against the New York Knicks on Sunday for arguing a foul call with referee Leon Wood.
The second of the two technicals, which carry with them a $2,000 fine apiece, has been rescinded by the NBA, according to league spokesman Tim Frank.
"Drew is usually a pretty mild-mannered kid, so that was unusual for him," Lakers head coach Phil Jackson said at Monday's practice. "That was a situation I think just exacerbated itself as the call went on. The first one was OK, the second one was not."
The Lakers have been hit with 15 technical fouls as a team in their past 10 games, dating back to playing the Milwaukee Bucks on Dec. 21. Kobe Bryant has been the main culprit with six, followed by Ron Artest, Derek Fisher and Matt Barnes with two apiece and Bynum (after one was rescinded), Pau Gasol and Luke Walton with one each.
"We just have to remain calm about it," Jackson said.
The NBA expanded its technical foul rule prior to the season to include issuing Ts for "overt" player reactions to referee calls.
"The [video] edit that we got from the league shows everything from genuflecting to referees and walking away and then praying before he blows the whistle," Jackson said of the instructional video the Lakers received before the season explaining the new rule. "That's probably the best thing you can do."
