The NBA is reviewing three plays from Wednesday night's games in order to determine if further penalty should be taken.
"The plays are under review," NBA spokesman Tim Frank said.
Derek Fisher bowled over Luis Scola as the Houston forward was setting a pick, which led to a Flagrant Foul 2. A suspension for Game 3 is under consideration.
Kobe Bryant elbowed Ron Artest as the two were angling for position on a rebound. If a player elbows another player above the shoulders, it is an automatic suspension by the NBA.
Replays appeared to show Bryant's elbow striking Artest on his upper chest, just above the "R" on Artest's Rockets jersey.
In the Magic-Celtics game, Rafer Alston slapped Eddie House on the back of the head following a three-point shot.
