WATCH: All Islanders vs. Predators highlights
The Predators (40-28-12) moved within one point of third place in the Central Division behind the St. Louis Blues, who were defeated by the Winnipeg Jets 5-2. Nashville tied the Calgary Flames for the first wild card from the West. The Flames lost to the Anaheim Ducks 3-1.
The Predators clinched a playoff berth for the third consecutive season on Sunday. Coach Peter Laviolette said he didn't feel the Predators were as sharp as they had been in a 3-0 win against the Minnesota Wild on Saturday and a 4-1 loss to the St. Louis Blues on Sunday.
"I'll be honest, I think when you clinch and you get that 'X' next to your name, you want to come out and play the same way," Laviolette said. "I do think it dropped a little bit. It didn't have the same bite and the same feel that the Minnesota game and the St. Louis game had."
Thomas Hickey scored 1:25 into overtime on a wrist shot from the right faceoff circle that beat Pekka Rinne. It was Hickey's fourth goal.
Hickey, a defenseman, played forward for the first time in his NHL career against the Predators. He was on a line with Brock Nelson and Josh Bailey.
"There's just more thinking involved than playing defense," Hickey said. "Obviously for me, even trying to have a nap this afternoon and just going over assignments in my head, I've never played the wing. At the end of the day, there's a few spots you can go to on the ice that are always going to be safe. It took me a few minutes to get my feet under me, and it's a different pace you play with, but it was a ton of fun."
Mike Fisher gave the Predators a 1-0 lead at 7:03 of the second period on a one-timer from the right faceoff circle. Colin Wilson took the puck wide and made a cross-ice pass that Fisher shot past Jaroslav Halak for his 18th goal.
Nelson tied it 1-1 at 1:32 of the third with his 18th goal.
