Coach Dan Bylsma indicated Monday that things have "gone the wrong way for him (Franson)...He's dealing with a strained neck and some other issues," John Vogl of The Buffalo News reports.
It appears Franson may still be a little ways from returning to the ice, though coach Bylsma didn't place a timetable on him. The blueliner makes an okay daily fantasy option when healthy (17 points, 92 shots on goal), but remains a fringe player in most season-long formats. Expect another update on him when he's set to rejoin the lineup.
