WASHINGTON — Wizards forward Kelly Oubre Jr. was suspended for Game 4 against the Boston Celtics after charging at and knocking over Kelly Olynyk in Game 3.

The NBA on Saturday announced Oubre’s suspension without pay for “charging and making forceful and unwarranted contact.” Game 4 is Sunday in Washington.

Oubre called the suspension a consequence of his actions.

“I’m not surprised,” Oubre said after practice Saturday. “The league has to do what they have to do. They have to handle that situation.”

Oubre’s outburst in the second quarter of Game 3 on Thursday resulted in a flagrant 2 foul and an ejection. Olynyk knocked him to the ground on an illegal screen, and Oubre leapt to his feet, sprinted at him and bowled him over.

The 21-year-old said he apologized to referee Monty McCutchen, who was talking to Olynyk at the time of the incident. Oubre said he did not reach out to apologize to Olynyk.

Washington Coach Scott Brooks said he respects the league’s decision and figured a suspension could be coming. Now he must decide how to approach Game 4 as his team trails Boston 2-1 in the second-round series.

“We’ve had a next-man-up mentality all year,” Brooks said. “We’ve got options, we can move some people around. But not having him, it’s not ideal, but it is what it is. You just go forward and play the game. You can’t worry about who’s not playing.”

Brooks could find more minutes for Bojan Bogdanovic after the sharp-shooting forward scored 19 points in the Wizards’ 116-89 victory in Game 3. Or he could plug another player into the rotation like Jason Smith.

“I’m looking at all options – maybe give some extra minutes, maybe add another guy, maybe change some spots on the floor with different players playing different positions,” Brooks said. “Those are all on the table right now.”

Brad Stevens stressed decompression.

His team had just been whacked, blown away by a 22-0 Wizards’ run in the first quarter of Game 3, and the Celtics coach made Friday’s team workouts optional.

“I hope some of them walk around D.C. and take a deep breath,” he said.

He needs a team that’s on the balls of its feet, instead of back on its heels, and the Celtics have yet to begin a game against the Wizards that way. The Wizards are averaging 39.7 points in the first quarter this series, including a 42-pointer in Game 2.

That inability to land the first punch finally caught up with the Celtics in Thursday’s Game 3 loss, when the Wizards managed to lock up the game with their early run.

In their 593 playoff games all-time that preceded this series against the Wizards, the Celtics allowed 38 or more points in the first quarter 10 times, according to stats guru Dick Lipe.

In the first three games against the Wizards, the Celtics have allowed 38 or more each time. These are record times, and as Stevens has pointed out, this has simply been how the Wizards impact opponents.

Especially the Celtics, though.

“No question that has been a major issue against them for most teams,” said Stevens.

“But the main thing is to stop talking about it and do it. They kicked our butt.”

Celtics President Danny Ainge and Stevens both were surprised by a WEEI report Friday that Isaiah Thomas is suffering from a broken jaw. The claim was made by talk show host and former Celtics radio announcer Glenn Ordway.

“He does not have a broken jaw,” Ainge said. “The jaw is for chewing and eating and moving, and (Thomas) is doing that.”

The guard, who had dental surgery prior to scoring 53 points in the Celtics’ Game 2 win, had an issue at halftime of Game 3. He was late coming out for the second half while having his dental work adjusted.

According to Ainge, the temporary bridge installed during surgery broke, forcing Thomas to return to the locker room, where the bridge was glued back together.
