Lin suffered the injury while driving to the basket during the fourth quarter of Brooklyn's 140-131 loss to the Indiana Pacers.
After the game, Lin posted the following tweet:
Prior to exiting the game, Lin had registered 18 points and four assists in 25 minutes as a starting guard alongside D'Angelo Russell.
Lin is in the midst of his second season with the Nets after bouncing around between five different franchises in six seasons previously.
In 2016-17, Lin averaged 14.5 points, 5.1 assists and 3.8 rebounds per game, but he was limited to just 36 contests due to injury.
Russell will take on an even greater ball-handling role with Lin on the shelf, while guards Caris LeVert and Spencer Dinwiddie are in line for additional playing time as well.
