That shot was a Darren Helm goal on a 2-on-0 that tied the game at 1-1 early in the first period. Nabokov appeared to hurt his lower body on the right side -- the Islanders later announced it as a groin injury-- as he went down for Helm's shot.
Poulin had started three consecutive games before Nabokov's return to the net. Nabokov had last played one week ago in a 4-2 loss in Columbus. By the looks of it, he won't be playing again for a while.
The Islanders are thin at the goaltending position in terms of pro-ready goalies. Anders Nilsson is under contract, but he's not having a great season for AHL Bridgeport. Kenny Reiter -- also in Bridgeport -- and Parker Milner with ECHL Stockton, are on AHL/ECHL deals.
Of course, the Islanders arguably could use help at the position even without Nabokov's injury. Their .898 overall save percentage ranked 26th in the league entering Saturday's action.
