Chicago Bulls superstar NBA MVP Derrick Rose is unsure about playing against the Celtic in a nationally televised game on Sunday. Rose had missed six games this year with toe and back injuries.

He sat out on Friday's game against the Charlotte Bobcats. C.J. Wilson replaced Rose for the night and lead the team to win 95-64 without Derrick Rose. 

Rose said his back remains stiff and sore and he would know more Sunday morning whether his condition improved enough to play on Sunday.  "When I wake up I can usually tell so I'll probably know by the time I wake up," Rose said.
