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.
I definitely think going back down helped me, I had a lot of confidence down there, I played a lot of minutes and I think that helped me a lot. With the 37 games up here, that gave me experience as well. I know what it takes to play in the NHL and now it's time for me to show that I'm capable of being a full-time NHL player.
