BOSTON — Celtics point guard Kyrie Irving has a broken bone in his face and is doubtful for their next game.

The team called the fracture minor.

Irving left Friday night’s game against the Charlotte Hornets in the first quarter after taking an inadvertent elbow to the face from teammate Aron Baynes. Irving was bleeding from the nose as he was escorted to the locker room.

Also Saturday, the Celtics said Al Horford probably would be able to return for Sunday’s game against the Toronto Raptors.

The Celtics have won 11 straight games, beating the Hornets on Friday night despite playing most of the game without Horford, Irving and Gordon Hayward.

Two nights after the sky appeared to be falling, and before Irving left Friday’s game, the Celtics received some good news on their injury issues.

The collective heart rate of Celtics Nation went up during Wednesday’s win over the Lakers when Jayson Tatum left in the second quarter because of a turned right ankle and was later put in a therapeutic walking boot. The rookie forward was back on the floor Friday, though, and helped big-time down the stretch, with six of his 16 points in the fourth quarter.

Perhaps the most curious aspect of the Celtics’ 11-game winning streak is the utter absence of practice time.

“It’s interesting. I think some players might echo this, some might argue it. But the less back-to-backs basically means it’s harder to practice, too,” said Stevens. “You don’t have that set day off and you don’t have sometimes those two days off in between games. You have more of this kind of every other day thing.

“So, you know, we try to do what we can with film, with individual work, with small group work, and walkthroughs,” he said. “But one of the things that we’ve gotta do is we’ve gotta play better than we did on Monday or Wednesday. And there’s a lot of technical things I think we can improve in.”
