If you were wondering if Kevin Shattenkirk had progressed past 95% yet, here is your answer:
Shattenkirk won't play Tuesday— Tom Timmermann (@tomtimm) November 2, 2015
Shatty is questionable at best for Wednesday night's game against the Blackhawks, though it stands to reason that if he isn't ready for Tuesday night's tilt against the Kings, he probably won't be ready for Wednesday night, either. The Blues' defensive corps has been holding down the fort fairly well without him, but he (amongst numerous others) have been sorely missed on the power play.
Odds are best for a return Saturday night against the Nashville Predators.
