Hamonic is dealing with a lower-body injury, which became public knowledge on Saturday.
It could be a bumpy ride to the All-Star break in general for the Islanders, as they may be without Hamonic and Johnny Boychuk for an extended period of time.
Head coach Jack Capuano was talking about depth moves when he called for roster tweaks after a frustrating loss, but does this signal a greater need for a more dramatic tweak?
If they mostly stand pat, this could be a challenging stretch for the Isles. They begin a three-game homestand when they host the Columbus Blue Jackets on Tuesday.
