Marcus Smart has been fined $35,000 for aggressively pursuing an opponent in an attempt to escalate a physical altercation and failing to leave the court in a timely manner following his ejection.

The incident, which took place after Smart was assessed his second technical foul and was ejected, occurred with 7:35 remaining in the third quarter of the Celtics’ 113-105 victory over the Atlanta Hawks on Jan. 19 at State Farm Arena.
