DEERFIELD—The big news in Saturday’s preseason game between the Bulls and Pacers is of course the return of Derrick Rose after nearly an 18-month absence. But while Rose is coming back, another Bull won’t be playing in Indianapolis, or for a while. Joakim Noah is going to miss some time.Even with it being a precaution, it’s more than the usual level of concern because Noah has missed so much time over the past year with plantar fasciitis. The two aren’t related, but groin injuries tend to be persistent. The good news is it really does sound like something that isn’t significant and unlikely to keep him out for any determined length of time. Meanwhile, Taj Gibson gets to start off his year guarding Roy Hibbert. Have fun guarding the guy five inches taller than you.
