Two nights after Jaylen Brown railed against what he viewed as unfair officiating in an NSFW rant, his head coach staged a different form of protest.

Clearly believing that Pascal Siakam set an illegal screen before his game-winning shot in the Pacers’ 98-96 win over the Celtics at Gainbridge Fieldhouse, Boston head coach Joe Mazzulla said only those two words in a postgame news conference that lasted less than a minute.

Mazzulla fielded six questions from reporters Monday night in Indiana, as seen on NBC Sports Boston, and replied “Illegal screen” to each of them.

Here is the full transcript of his 44-second presser:

Reporter: Joe, you gave yourselves a chance to win. Take us through the last couple possessions.

Mazzulla: “Illegal screen.”

Reporter: What?

Mazzulla: “Illegal screen.”

Reporter: Illegal screen?

Mazzulla: “Illegal screen.”

Reporter: What fell apart to get you guys behind, and then how were you able to get back in the game?

Mazzulla: “Illegal screen.”

Reporter: What do you mean by that? What do you want people to know about–

Mazzulla: “Illegal screen.”

Reporter: Would you like to say anything else?

Mazzulla: (pauses) “Illegal screen.”

On the play in question, Siakam set a screen on guard Derrick White to force a switch away from a longer wing defender, Jordan Walsh. Siakam then received a pass from Andrew Nembhard, posted up White, spun past him and banked in a floater to break a 96-96 tie with 6.8 seconds remaining.

White had a chance to answer on the ensuing possession, but his deep 3-pointer rang iron as time expired.

The Celtics were playing without Brown, who missed the game with low back spasms, and shot the ball poorly in their leading scorer’s absence, making just 26% of their threes (9-for-35). The loss to the last-place Pacers was Boston’s third in four games.
