Collison (knee) will undergo an arthroscopic procedure on his left knee and will miss the next 2-to-3 weeks, Harrison Wind of BSN Denver reports.
EDGE Analysis
Collison was listed as questionable for Monday's game with a bruised left knee, but the issue is apparently more serious, and he'll undergo surgery -- albeit relatively minor surgery -- in the coming days. Expect Collison to return shortly after the All-Star break, and in the meantime, Cory Joseph figures to fill in as the starter.
