Senators' Clarke MacArthur: Helped off ice Sunday

MacArthur required assistance leaving the ice after taking a hit from Patrick Sieloff in Sunda's scrimmage, Brent Wallace of TSN reports.

Analysis:

This is especially concerning given that he missed most of 2015-16 with a concussion, though the diagnosis of this injury has yet to be confirmed. More information on his status should arise in the coming days.
