Bynum and Brooks were involved in separate March 18 incidents.
Bynum drew a two-game suspension for committing a flagrant foul against Minnesota forward Michael Beasley with 6:16 left in the fourth period of the Lakers' 106-98 victory over the Minnesota Timberwolves.
He was set to miss Sunday's game against Portland and a March 22 contest against the Suns.
Brooks, meanwhile, garnered a one-game suspension for throwing a ball toward a game official, hitting him in the leg in the fourth period of Phoenix's 108-97 win over Golden State.
Brooks was to miss the Suns' game at the Los Angeles Clippers Sunday.
