What It Means:

Butler's knee injury was worse than expected and fantasy owners will now be without Butler until what sounds like the beginning of March at the earliest. While Butler is worth holding in standard leagues for now, E'Twaun Moore, Tony Snell, Doug McDermott, and Mike Dunleavy will all see extra minutes, with Moore being the priority add.

This is a massive blow for the Bulls. Butler ranks eighth with a 12.2 nERD in 48 games played this season. He's averaging 22.4 points, 5.2 rebounds, 4.3 assists, 1.7 steals and 1.1 3-pointers per contest.
