The 7-foot Bosnian collapsed to the hardwood while coming down from a putback attempt after appearing to land on Nets wing Jared Dudley's foot with 2:22 remaining in the period. The Blazers later said Nurkic suffered a compound fracture of his left tibia and fibula and will miss the remainder of the season.
Fans at Moda Center chanted Nurkic's name as trainers tended to him under the basket and covered his injured leg with a towel. The big man was eventually loaded onto a stretcher with the assistance of several teammates.
Before leaving, Nurkic had recorded a double-double of 32 points and 16 rebounds on 13-of-24 shooting in 34 minutes. He also had five assists, two steals, and four rejections.
Following Portland's narrow 148-144 victory, head coach Terry Stotts informed reporters that Nurkic had been transported to a local hospital and described the injury as "devastating," according to NBA.com's Casey Holdahl.
"It made me sick to my stomach," Blazers guard Damian Lillard added of the injury, according to the Oregonian's Joe Freeman. "I was playing at the (United States national team) game in Vegas when a similar thing happened to Paul George. That's exactly what it looked like to me when I saw it. You never want to see that happen to anybody, let alone your friend and teammate."
Following the injury, the Trail Blazers clinched a playoff berth for the sixth consecutive season with the victory. They currently sit fourth in the Western Conference with a 46-27 record.
