TORONTO — Doc Rivers has acknowledged the 76ers are concerned about Joel Embiid’s right thumb.

“But you know, it is what it is,” the Sixers coach said ahead of Saturday’s 110-102 loss to the Toronto Raptors in an Eastern Conference first round at the Scotiabank Arena.

The good thing for the Sixers is that Embiid’s thumb can’t get worse, according to Rivers. The bad thing is that the MVP runner-up has to play in a lot of pain and discomfort.

Embiid underwent a test that suggests he has ligament damage in his thumb.

He will undergo an MRI on Sunday to confirm the injury.

“We could see how bad it really is,” Embiid said. “But as always, when I go out, I don’t really worry about what may happen. I just want to do whatever I can, focus on whatever I can focus on.

However, his thumb was sore on Saturday. Sometimes he would visibly writhe in pain and/or shake his hand after hitting it.

Perhaps because of the pain, Embiid didn’t seem committed in Game 4.

He missed all five of his shots and had just one point in the first quarter. Embiid then finished with 21 points on 7-for-16 shooting to go with eight rebounds, three assists and five turnovers. He attempted nine free-kicks, making seven.

But the dominant player was basically a non-factor while having 16 points while making 2 of 3 foul shots and grabbing three rebounds in three quarters.

“I wish it had happened on my other hand and not my shooting hand,” said Embiid, who is right-handed. “But you know I’ll adapt. Guess I’ll have to use my left hand even more than usual. “

He slightly modified his free throw routine by not clapping his hands. He admitted it had an impact on his free-throw play, rebounding and passing the ball.

“It’s going to be something he’ll have to deal with all the way through the playoffs from now on,” Rivers said. “It’s not going away, you know? Thus, he will know how to use it better and better.

The Sixers will manage the injury as best they can, but it’s all up to him. Embiid picked up the injury in the first half of Game 3. He was the hero of the night, draining a game-winning three-pointer with 0.8 seconds left.

The adrenaline that night helped him pull through.

But how he plays through the injury now depends on his pain tolerance. He will either be a soldier and not let it affect them. Or it could totally ruin it.

The Sixers will look to clinch the series in Game 5 Monday night at 8 p.m. at the Wells Fargo Center.

In advancing to the second round, they will face the series winner Miami Heat vs Atlanta Hawks. The Heat still led that series, 2-1, after the Hawks came back and won Game 3, 111-110, on a late bucket from Trae Young. Game 4 at 7 p.m. Sunday in Atlanta.

The Sixers’ second-round opponent could potentially benefit from Embiid’s injury if it continues to bother him. And even if they don’t target his thumb, his hand will be repeatedly hit, grabbed, stuck in singlets, and banged trying to defend himself.

And the thumb won’t improve in the playoffs if it’s actually torn.

In addition to confirming Embiid’s injury, the MRI will show how intact the thumb is. If it is not torn, it may be a sprain or an avulsion fracture.

A specialist would most likely recommend surgery if it is confirmed to be torn.

“I want to play,” Embiid said. “Obviously I have to listen to what they have to say. So I imagine I’m still playing and probably doing something after the season.

He had been battling an illness in Games 1 and 2 of the series. But this disease does not compare to the pain he plays with now.

Embiid believes he injured his thumb when his hand got caught in someone’s jersey in Game 3. There were times in Saturday’s game when he doubled over in pain or held his hand. hand after hitting it. Embiid was asked how bad the pain was at those times.

“Africans don’t feel pain,” the Cameroonian said with a smile.
