The Nets were undermanned, undersized and, in the end, overwhelmed.

Pushed around in the paint and battered on the boards, the Nets suffered a 100-92 loss to Orlando before 16,505 at Barclays Center on Sunday.

“Extremely physical team. We had to find a way to get more…a better rhythm, and play a little faster and get quicker shots — and we couldn’t. So they deserve the win,” coach Jordi Fernandez said. “We fought until the end, and we got to play them one more time. So that’s a fun part about the NBA, is we play this team four times. Let’s see how much better we can be by the time we play them again.”

The Nets (9-12) were better this time than the two meetings earlier this season when they got drilled by a combined 38 points. They surrendered 29 points to Franz Wagner in each previous loss, Oct. 25 in Orlando and Friday at home.

Sunday was much more competitive. The Nets got a game-high 25 points from Cam Johnson and held Wagner to 4 of 17 from the field and 0 of 6 from deep.

But their frontcourt woes and ineffectiveness on the glass undid them against the Magic (15-7).

Playing without Cam Thomas, Dorian Finney-Smith, Noah Clowney and Day’Ron Sharpe, the Nets also saw Ben Simmons exit with a knee contusion. They were outrebounded, 52-33, and outscored in the paint, 54-38.

“They’ve got two guys who were in there who are a lot bigger than guys we have out there, so that’s always gonna play a role. But we have to [find a way],” Simmons said.

“They’re a physical team, and they bring the fight to you. They try to pressure you, get you out of your stuff,” Johnson said. “We just gave up a couple too many baskets, and they got some transition [points] and some easy looks, offensive rebounds. [The] rebounding game was tough for us.

“It’s not really an excuse at the end of the day. We have five guys on the court and we’ve still got to rebound. And it starts with me. I probably had three or four go right through my hands. … It was a big part of the events of [Sunday].”

Sunday saw the Nets drop their fifth straight to the Magic and fall to 3-11 against the East.

Dennis Schroder returned from personal leave with 20 points and seven assists, though he had six turnovers and shot just 6 of 19 from the field and 1 of 6 from deep.

The Nets struggled against Orlando’s size and physical defense, shooting 38 percent and 8 of 31 from 3.

The game was knotted at 83-all before the Magic broke the deadlock for good with a 3 from Kentavious Caldwell-Pope (16 points).

Schroder fed Johnson for a fast-break dunk to cut the deficit to one. But the Nets allowed six unanswered points and never challenged again.

A Wendell Carter Jr. dunk made it 88-85 Orlando. Then Schroder got whistled for a charge on Wagner, and Carter (14 points, seven rebounds) made a pair of free throws.

After Nic Claxton had a bad pass stolen by Caldwell-Pope, the Magic wing scored a layup the other way. The Nets trailed, 92-85, with 4:09 left and never recovered.

The Nets lost Claxton and Johnson with 18.1 seconds to play, the former ejected for a Flagrant 2 on Wagner and the latter departing due to a tweaked ankle.

The Nets enters Chicago on Monday licking their wounds, having been pushed around physically and being vexed by the refs — despite the fouls (31-29) and free throws (32-31) being fairly even.

“The refs were blowing the whistle too much. They were having too much of an impact on the game,” Simmons said.

“There’s a lot of frustration and frustration on the players, myself, and the only thing I can say is to ask my players not to complain and keep going,” Fernandez said. “So we’re going to keep fighting, whether it’s against five or more.”
