Kris Dunn done for the season?

The Bulls haven’t officially updated Dunn’s status since Feb. 4 when they said the guard’s sprained right MCL would be re-examined in two weeks. But sources said there’s growing belief that Dunn will miss the remainder of the season with the injury, which occurred when Thaddeus Young took a charge and inadvertently crashed into Dunn’s knee on the first possession of a Jan. 31 road game against the Nets.
