Brooklyn Nets coach Steve Nash has praised Kyrie Irving and his side's team effort after their win over the New Orleans Pelicans on Tuesday as doubts grow around James Harden's return.

The Nets edged past the Pelicans 134-129 on Tuesday without key pair Kevin Durant and Harden, with the latter now unlikely to return prior to the play-offs with a hamstring setback.

Brooklyn have only managed to field the 'big three' - Durant, Harden and Kyrie Irving – at the same on only seven occasions due to injuries.

But the Nets improved to 39-19, keeping the pressure on the Philadelphia 76ers at the top in the Eastern Conference.

Irving scored 32 points and had eight assists, while forward Joe Harris hit 24 points with Jeff Green contributing 15 along with nine rebounds and six assists.

Guard Landry Shamet was one of three players to have six or more assists, with eight along with 18 points.

Blake Griffin added 16 points and eight rebounds off the bench, along with Bruce Brown Jr with 11 points and 11 rebounds.

"When Ky was out of the game I thought we played very well," Nash said.

"When we're going into a game with nine men, you're a couple superstars down, you've got guys playing with more responsibility and minutes and if they don’t play well, you can find yourself in a big hole.

"They played really well. Really proud of the way the guys played. I think we started slow because it was nice, new line-up, new combination."

Nash did reserve special praise for Irving who was clutch down the final stretch with some key buckets along with a late steal off Zion Williamson in a tight game.

"He made some really difficult shots," Nash said. "There wasn’t a ton of movement on the last three possessions.

"Tip your hat to your star player who makes the shots but our guys were terrific all night."
