EAST MEADOW, N.Y. — The Islanders gathered Friday for their annual team photo at their new practice center, which is close to Nassau Coliseum, their former rink. They were all smiles, though their mood was surely tempered by the knowledge that they would be without their top defenseman, Travis Hamonic, who was injured during Thursday’s win over Columbus. The Islanders are also concerned about a key element where they now play — namely, poor ice conditions at Barclays Center in Brooklyn.

Players complained about the ice after the 4-3 victory, saying it was sluggish, especially late in the game. Unseasonably warm temperatures that day might have contributed to the problem, though similar complaints were heard early in the season at Barclays, which was not originally designed to accommodate a hockey rink.

“The ice was horrendous,” defenseman Thomas Hickey said after the game. “It was pathetic, worse than it was last game. It must be tougher with weather getting better outside.”

He added, “It hurts the product, and that’s not right.”

The Islanders’ captain, John Tavares, said soft ice could cause problems on every shift.
