NBA superstar Kevin Durant led from the front with 53 points to inspire the Brooklyn Nets to a 110-107 narrow victory over the New York Knicks Sunday while teammate Kyrie Irving, who cannot play due to COVID-19 vaccine regulations, watched on as a spectator.

New York City's private sector vaccine mandates mean Irving still can't play NBA games in New York, at either the Nets' Barclays Center or the Knicks' Madison Square Garden.

But relaxed rules for the unvaccinated in public spaces meant he could attend the game as a fan – an anomaly that prompted a frustrated comment from NBA rival LeBron James.

"It literally makes ABSOLUTELY ZERO SENSE!!!" James tweeted as pictures of Irving courtside made the social media rounds. "They say if common sense was common then we'd all have it. Ain't that the truth."

Durant agreed.

"It's ridiculous," Durant said after the game. "I don't understand it at all. There's a few people in our arena that's unvaxxed, right? They lifted all of that in our arena, right? So I don't get it.

"It just didn't make any sense. We got a guy who can come in the building. Are they fearing our safety? I don't get it. We're all confused. Pretty much everybody in the world is confused at this point. Early on in the season people didn't understand what was going on, but now it just looks stupid."

Without Irving, who so far this season has been limited to playing away games and with new acquisition Ben Simmons yet to make his Nets debut, it was again up to Durant to carry Brooklyn.

Despite defensive pressure from the Knicks, Durant was one shy of his career-high scoring night with six rebounds and nine assists as Brooklyn won a sixth consecutive meeting over New York.

Durant drilled a 3-pointer with 56.3 seconds remaining that pulled Irving out of his seat and put the Nets up for good at 106-103.

"Kevin was unbelievable," Nets coach Steve Nash said. "Carried us. Made a lot of big plays. Rebounds, assists, the whole deal. He was Kevin Durant on full display."

Durant posted the eighth 50-plus point game of his career and his second this season.

Only two other players, Irving and James, have reached the half-century mark in at least two games this season.

The Nets hope changes in regulations will allow Irving to play home games once the playoffs start on April 16.

NBA Commissioner Adam Silver is among those who say banning Irving while unvaccinated visiting players can take the court in New York "doesn't quite make sense."

New York City Mayor Eric Adams removed the public sector vaccine and mask mandates in February so that the unvaccinated were allowed in public spaces such as bars and venues like the Barclays Center.

But a private-sector mandate requiring employees of New York-based businesses to be vaccinated remains in place, and no exception will be made for Irving, Adams saying it would "send the wrong message."

"It just feels like somebody's trying to make a statement or a point to flex their authority," Durant said. "Everybody out here is looking for attention and that's what I feel like the mayor wants right now, is some attention. But he'll figure it out soon – he better.

"Eric, you got to figure something out man, because it's looking crazy ... he can come to the game, but not play? Come on, man."

LeBron reaches 30-10-10

James reached a milestone in the Los Angeles Lakers' 140-111 loss at Phoenix.

James became the first NBA player with 30,000 career points, 10,000 career rebounds and 10,000 career assists with his second assist of the game, a pass to Carmelo Anthony.

Luka Doncic had 26 points, eight assists and eight rebounds and Spencer Dinwiddie hit the decisive 3-pointer with 11 seconds remaining to lift Dallas over host Boston 95-92.

It was the Mavericks' sixth triumph in seven games and snapped Boston's five-game win streak.

The Celtics retired the No. 5 jersey of Kevin Garnett after the game. The 45-year-old Hall of Fame big man was NBA Defensive Player of the Year in 2008 when he led Boston to the NBA title.

Joel Embiid scored 35 points and grabbed 16 rebounds while James Harden and Tobias Harris each scored 26 points as Philadelphia edged Orlando 116-114 in overtime.

Trae Young scored 47 points to lead Atlanta over Indiana 131-128 while Marcus Morris scored 31 points to lead the Los Angeles Clippers over host Detroit 106-102.

Ja Morant had 17 points and 10 assists for Memphis in a 125-118 triumph at Oklahoma City while Jonas Valanciunas had 32 points in New Orleans' 130-105 victory over Houston.
