Islanders defenseman Travis Hamonic left Saturday's game against the Oilers after blocking a shot with his arm in the first period and did not return.
After blocking a shot from Oilers forward Patrick Maroon at 12:13 of the first period, Hamonic grabbed his arm and skated off the ice, missing the rest of the game.
The Islanders did not give a timetable for the injury, but Newsday's Arthur Staple said the Islanders could be missing Hamonic "for a while."
According to Staple, if Hamonic misses time, defenseman Adam Pelech is likely to get recalled from the AHL.
Hamonic has two goals and three assists in 12 games this season as a top-pairing defenseman with Nick Leddy.

This is a huge blow for the Islanders, who were struggling to begin with, as they now will have to deal without, arguably, their top all-around defenseman. The hits just keep on coming, as this was a freak play where an elevated wrist shot bounces off the D-man, heads right to Leon Draisaitl, who puts it into the half open net.
In a text late last night, SNY.tv was told Hamonic is "out a while," leading to the belief that it is indeed a broken bone, which could keep him on the shelf for 4-to-6 weeks.
A message obviously got to Bridgeport head coach Brent Thompson immediately, which is never a good sign, as he sat Pelech for the entire third period of the Sound Tigers' 7-1 loss to the Wilkes-Barre/Scranton Penguins.
Pelech, who had a fantastic training camp, is expected to be recalled Sunday and join the team for Monday night's game against the Vancouver Canucks in Brooklyn.
