The Philadelphia 76ers have been a thorn in the side of the Wizards all season, winning 2 of 3 meetings. Sunday, they did them a big favor by coming from 13 points down to upset the Boston Celtics.

This sets the stage for Monday’s pivotal matchup when the No. 3 Wizards play at the Celtics. They lead the season series 2-1 and a victory would give them the tiebreaker in the event they have the same records going into the playoffs.

“We were talking about, a few guys overlooking this game. I think so, looking forward to the Washington game,” Jae Crowder told reporters after a 105-99 loss for Boston. “That’s what happens when you overlook an opponent, especially these guys.”

The Wizards (42-27) lost 96-93 to the Charlotte Hornets on Saturday to drop two games out of the No. 2 spot occupied by Boston. But the loss to the Sixers puts the Celtics (44-26) just one game ahead in the loss column.

Boston played the last two games without Isaiah Thomas who stayed behind on the road trip because of a bruised knee.

The Sixers had to make the third-quarter comeback without Jahlil Okafor, who left with soreness in his right knee.

According to CSNPhilly.com’s Jessica Camerato, the Sixers Insider, Okafor will be further evaluated.
