Noah, Gibson, Nocioni, and i'm pretty certain Rose and Boozer have all had plantar fascitis.
Putting a positive spin on Rip's injury:
1) gives Marco/Jimmy more minutes, hopefully they take advantage of it
2) gives Rip a short window of rest in an 82-game season
3) it's early in the season and isn't a serious injury that should have him miss more than 1 week or so
This is a week to week injury, meaning he could miss up to 2-3 weeks. Still not a HUGE injury but one that could still affect him once he returns.
