Hamonic left Tuesday's game versus the Senators with an upper-body injury, the Associated Press reports. Hamonic will most likely take Wednesday's practice off while he recovers from the injury, so it might not be known until after Thursday's morning skate whether or not he'll suit up for the rematch with the Senators. His potential absence for that game would be damaging, as the Islanders have already been getting by without Lubomir Visnovsky (upper body) and Johnny Boychuk (upper body).
