Lakers forward Matt Barnes was suspended one game for his role in the altercation during Thursday night's game against the Mavericks.
Mavericks guard Jason Terry and center Brendan Haywood and Lakers guard Steve Blake were also ejected after the incident with 9:23 remaining in the game, but Barnes is the only one who was suspended.
NBA executive vice president Stu Jackson cited Barnes "for escalating an on-court altercation and actions following his ejection" in announcing the suspension.
The altercation began when Terry committed a flagrant foul by shoving an off-balance Blake in the back. The league downgraded that from a flagrant 2 to a flagrant 1 after reviewing the incident.
As Blake and Terry exchanged heated words, Barnes ran across the court and escalated the argument by shoving Terry. Referee Joey Crawford shoved Barnes toward the Mavs' bench in an attempt to get him away from Terry.
Mavericks assistant coach Terry Stotts wrapped his arms around Barnes from behind in an attempt to calm him down. Barnes responded by shoving Stotts to the floor, saying after the game that he didn't know who was grabbing him.
"One of their coaches grabbed Matt," Lakers coach Phil Jackson said. "That's not what you do. You grab your own players. That's kind of the rule of the game."
It isn't clear what Haywood did to merit being ejected.
