Hickey, 24, made his NHL debut last season and had four points and a plus-9 rating in 39 games. He appeared in two of the team's six Stanley Cup Playoff games against the Pittsburgh Penguins. The Los Angeles Kings made Hickey the No. 4 pick in the 2007 NHL Draft, but after playing 212 games with the Manchester Monarchs in the American Hockey League, Hickey was waived and claimed by the Islanders on Jan. 15.
