James Harden believes Brooklyn Nets have found good chemistry on the court despite the absence of key men Kevin Durant and Kyrie Irving.

Brooklyn Nets coach Steve Nash said Durant will not be risked for road games against Utah Jazz and Detroit Pistons this week but is the final phase of rehabilitation.

Durant has been sidelined by a hamstring strain since mid-February and was absent from the team that topped the Portland Trail Blazers 116-112 on Tuesday.

The 32-year-old averages 29 points, 7.3 rebounds and 5.3 assists from 19 games, but Nash said he will be absent again for the trips to Utah and Detroit on Wednesday and Friday respectively.

Harden led the way for the Nets against the Trail Blazers with a double-double as they go toe-to-toe with Philadelphia 76ers the Eastern Conference.

He posted 25 points and a career high-tying 17 assists to fuel the Nets in Portland as they won without Durant and fellow superstar Irving, who was absent for personal reasons.

Harden claimed the Nets have clicked into gear ahead of meeting with the Jazz on Wednesday.

"The team chemistry, it's there. It's right where we need it to be," the 31-year-old told NBA.com

"Obviously missing Kevin and Kyrie, I think everyone else has a sense of what their roles are, and they're doing it to the best of their ability every single night. 

"I'm really proud of the guys. In order to be a special team like we're more than capable of being, we've got to have a sense of urgency every possession.

"Our sense of urgency in the way we play and our effort and our intensity on the defensive end, has to be there no matter what."

On the Jazz's recent improvements Harden added: "I think they're healthy. They're healthy and they finally have clicked.

"I think that loss in the playoffs in the bubble last year got to them a little bit and so they have a fully healthy team that's well coached and everybody knows their role and they have a great system and it works for them."

The Nets (30-14) remain within a game of the Eastern Conference-leading Philadelphia 76ers (31-13) who held on to beat the Golden State Warriors 108-98 on Tuesday.

Behind Tobias Harris' 25 points and 13 rebounds and Ben Simmons' 22 points, the 76ers earned their fifth consecutive road victory – the team's longest winning streak away from home since winning seven straight in 2018.

76ers coach Doc Rivers was pleased with the natural rhythm to the way in which Harris performed as he turns his attention to Thursday's game with the LA Lakers.

Rivers said: ''What I liked about his game, he didn't force it, he kind of just let the game come to him. And he made plays, not just with his shot but with the pass.

''As a group, we've won nine out of 10 games, the guys are playing good basketball - no need to talk about it."
