Boston's Kevin Garnett could be suspended for Game Five against the Hawks if it is determined that he threw an elbow at referee Eddie F. Rush, according to the Atlanta Journal-Constitution.

Garnett and Zaza Pachulia of the Hawks both received technical fouls during an altercation just before halftime of Game Four on Monday.

The league is also looking into whether or not Kendrick Perkins and Marvin Williams left the bench during the incident, which could also lead to suspensions.
