Ennis (upper body) will not be in the lineup against Montreal on Tuesday, Bruce Garrioch of the Ottawa Sun reports.
Ennis was starting to find some offense of late with three points in his last four contests, though he did manage just two shots over that stretch as well. If the veteran winger can avoid an extended absence, he could still reach the 30-point threshold for just the second time in the last seven seasons. In his stead, Parker Kelly was called up from the minors and will jump into a bottom-six role versus the Habs.
