Bulls' Derrick Rose out again Feb 12 04:27 PM US/Eastern BOSTON (AP) - Chicago guard and reigning MVP Derrick Rose will be sidelined Sunday for the Bulls' game against the Boston Celtics. Bulls coach Tom Thibodeau said about an hour for the game that Rose still has some stiffness in his back and will see a specialist when the team gets back to Chicago on Monday. Rose also missed Friday's win at Charlotte with what the team called a "strained lower back." He originally was hurt earlier in the week and was limited in a win over New Orleans.
