It could have been incidental contact, but the officials deemed it something else.
What looked to be an innocent play made the Pistons shorthanded for the second half of Saturday's 113-104 loss to the Boston Celtics. Hamidou Diallo was ejected in the second quarter after making contact with an official.
Diallo was saving a ball from going out of bounds and turned to run up court. Diallo looked to be trying to get his balance and ran into the official, Suyash Mehta, who immediately called a technical foul.
After video review, the officials determined that the contact was intentional, and Diallo was ejected.
