Guess what NBA STAR is back hurt! Derrick Rose

Derrick Rose will not play Saturday afternoon in Brazil because he's suffering from left knee soreness, according to the Chicago Tribune's K.C. Johnson.

Rose and Joakim Noah are sitting out the Bulls' game against the Wizards, and they'll be replaced in the starting lineup by Kirk Hinrich and Nazr Mohammed. The big news is obviously Rose's knee, because this is the first hiccup since he started playing on his surgically-repaired left knee.

The team said sitting Rose is just a precautionary move, but every bit of Rose news that isn't "he's 100-percent healthy" is concerning for Bulls fans, who sat through a season of speculation about the actual health of Rose's knee. The Bulls will handle this with the greatest of care since the games don't count.
