The aftermath of Wednesday night’s brawl with the Brooklyn Nets could be costly for the Celtics, who may lose Rajon Rondo for multiple games if the league office levies a suspension.

Rondo and Brooklyn’s Kris Humphries were the central figures in a fight that spilled into the stands under the east basket with 29.5 seconds left in the first half. The NBA frowns upon 1.) altercations that spread into the stands and 2.) actions by repeat offenders.
