Joakim Noah

Joakim Noah has a reputation as a free spirit, but he remained a missing one Sunday.

Bulls coach Tom Thibodeau said his starting center missed a second consecutive day of training camp for ‘‘personal reasons.’’

‘‘Just a personal matter,’’ Thibodeau said. ‘‘He’ll be out a couple days. Hopefully he’ll be back [Monday].’’

Noah spent a few weeks in the offseason working with NBA legend Kareem Abdul-Jabbar, especially on offense, so it would be nice for the Bulls to have him back for the preseason opener Tuesday.
