SAN FRANCISCO – The Nets added Cam Johnson and Cam Thomas to their injured list, forcing both to miss Monday’s win.

Brooklyn was already without Nic Claxton, Dorian Finney-Smith, Ben Simmons and Noah Clowney.

But Johnson sprained his right ankle in the first quarter when he landed on Draymond Green’s foot, and limped through the final 7:22 of the first half before not returning in the second.

The Nets had no update on his status.

Thomas had 23 points but was pulled with 6:43 left in the third.

He missed the Charlotte game with a sore back, was ill in Philadelphia on Friday to start the road trip and was rested by Jordi Fernandez.

“I ended up taking him out because he fouled, he was tired,” Fernandez said. “I didn’t think it was right. And I just wanted to protect him from himself.”

Simmons rested Monday as he has not been cleared for back-to-backs, but is expected to return to Phoenix on Wednesday.

Finney-Smith (ankle) and Claxton (back) are both TBD against the Suns, who get Kevin Durant back on Tuesday night.

After an up-and-down start to the season, Clowney had the best performance of his career in Sunday’s 108-103 win in Sacramento and was promptly injured.

He missed the end of the back-to-back against the Warriors with a sprained left ankle.

Clowney had an MRI, the results of which were not known due to a tip from Chase Center, and Nets coach Jordi Fernandez was unsure if the youngster had major x-rays.

‘It could be worse, and it is not worse. So I’m happy,” Clowney said.

Claxton’s back is watching.

He first injured it over the summer, calling it a “long-term thing” and acknowledging that he will “probably stick with it for a while.”

Neither Claxton nor Fernandez could say what “a while” meant.

“In professional sports, especially in this league, a lot of these guys play with bumps and bruises. What we need is for them to believe they are ready to go,” Fernandez said. ‘And if we feel like a man lacks self-confidence, we let him make the decisions. I think that’s fair. If you play and are afraid of getting hurt, you will get hurt. So we don’t want that for Nic or anyone else.

“We’re going to help him gain confidence, and when he’s on the field it’s because he feels 200 percent. So that’s where we are now with Nic.”

Ziaire Williams had to start as a small-ball center while injury-plagued Brooklyn played five-out.

He had his second career double-double with 17 points and 10 boards.

He didn’t remember playing in the NBA or in college.

“Shoot guy, probably high school. In high school I was a center,” Williams said. “It’s fun, man, I just love playing, competing. Whatever the coach wants me to do, I just go out there and give my full effort.”

The turnovers were essentially even, but Brooklyn outscored the Warriors 26-13, after turnovers.

“The coach wants to play fast. In the first six seconds he wants to shoot the ball,” said Dennis Schroder.

Brooklyn recalled Long Island’s Dariq Whitehead, for whom he scored 26 points in Toronto on Sunday.

“Every game I’m starting to trust my body more and more and the stats clearly show that,” said Whitehead. “But for me it’s mainly about staying consistent. I have to keep it consistent.”
