Premise: Borowiecki suffered an upper-body injury against the Canucks on Tuesday and won't return, Bruce Garrioch of the Ottawa Sun reports. Borowiecki was a game-time decision for the roster, but this wasn't due to Erik Karlsson (foot) returning, not health reasons. The 28-year-old is best known for his defensive abilities and willingness to get physical, and he isn't suited for most fantasy formats.
Hypothesis: an upper-body injury happened that caused the man to not return
