Some people wondered whether Nathan Horton blocked a shot off his wrist or suffered a separated shoulder during the first overtime of Chicago's 4-3 3OT win over Boston last night. Whatever really happened, we won't know until after the series, if we are ever told what happened, but for the moment, TSN and the Canadian Press report the usual kind of injury update at this time of year from Bruins coach Claude Julien:

Boston Bruins coach Claude Julien said Thursday that forward Nathan Horton is day-to-day with an apparent upper-body injury.

Horton left the Bruins' 4-3 triple overtime loss to the Chicago Blackhawks on Wednesday in the first overtime period.

"Fingers crossed at the end of the day that he's back for next game," Julien said according to the Bruins' official Twitter feed.
