Operation Sports' Steve Noah grabbed an image of the injury:
Amick later reported that Fisher returned to the bench after getting some medical assistance:
While Fisher doesn't play a huge role for OKC, his team needs all the help it can get to overcome a 2-0 series hole. The Thunder are facing a must-win game Sunday night, and not having Fisher there to back up Reggie Jackson at the point makes their job that much harder.
The 39-year-old showed in Game 1 that he's still capable of having a hot shooting night. He scored 16 points in Oklahoma City's 122-105 loss, knocking down four of his six three-point shots.
Fisher can also be a calming presence on the floor for Kevin Durant and Russell Westbrook when things start going wrong for OKC. The five-time NBA champion knows what it takes to prevail in the postseason.
Given the rather innocuous nature of the injury, Fisher shouldn't spend too much time off the floor.
