Hamonic has missed the past eight games since sustaining a concussion during a game Jan. 12 against the Dallas Stars.
To fill his roster spot the Islanders recalled Donovan, who had been sent down a day earlier to clear a roster spot for defenseman Lubomir Visnovsky, who returned from a three-month absence due to a concussion to play Monday against the Boston Bruins.
Donovan has six points and a minus-10 rating while averaging 17:30 of ice time per game in 32 games.
It was a different game in the past, that's for sure. It's not exactly what I was expecting but I think the experience paid off for a lot of our guys that realized what it takes in a Game 7. Realistically the effort we put forward, we might not even had to put 60 [minutes], but we just couldn't get a couple bounces to go our way and we just kept pushing.
