Brooklyn Nets head coach Steve Nash admitted he is concerned with Kevin Durant's workload, describing it as "not safe or sustainable".

Before Thursday's 114-105 win over Eastern Conference rivals the Philadelphia 76ers, Durant ranked second in minutes per game (36.9) this NBA season.

The shorthanded Nets, who have been hit by a COVID-19 outbreak, have relied heavily on their superstar in 2021-22 – Durant played a season-high 48 minutes in Tuesday's overtime victory against the Toronto Raptors.

Not since 2013-14, during his time with the Oklahoma City Thunder (38.5), has former MVP Durant averaged more minutes per game in his illustrious career.

"It's a really important topic," Nash before the Eastern Conference-leading Nets outlasted the rallying 76ers in Brooklyn, with Durant playing a team-high 39 minutes.

"I don't know we can continue to lean on him the way we have. It doesn't feel right.

"I know he's enjoying it. I know he's enjoying playing at the rate he's playing at and trying to bring his team-mates along with him and all the responsibility that he's accepted and crushed, basically.

"It's just been incredible. But, at the same time, it's not safe or sustainable to lean on him like that. There's gonna be a lot of consideration and we'll have to figure out ways to give him breaks."

Durant was ice-cold against the 76ers, posting 34 points – including a pair of three-pointers, 11 rebounds and eight assists to lift the Nets.

The Nets are top of the Eastern Conference with a 21-8 record, two and a half games clear of defending champions the Milwaukee Bucks.
