Bulls' Rose out vs. Celtics

Chicago Bulls point guard Derrick Rose will miss Thursday's game against the Celtics with a sore back.

Rose will sit out his fourth straight game due to the ailing back, though an MRI on Monday revealed no structural damage.

Still, it has been an issue of late. He left a lopsided win over New Jersey on February 6 after playing only 11 minutes, then played just 22 minutes in a rout of New Orleans two days later before missing the last three games.

He has also missed time this season because of a toe injury and is averaging 22.0 points, 7.8 assists and 3.4 rebounds in 23 games.
