Forward Rickard Rakell, who led the Ducks with 33 goals in the regular season, missed Game 5 because of a lower-body injury and is day to day.
The Predators, however, were without two leaders, forwards Mike Fisher and Ryan Johansen, and Johansen is out for the rest of the playoffs after having surgery on his left thigh.
"It's playoff hockey," Ducks captain Ryan Getzlaf said. "You look at their lineup and they're depleted as well. That's the way playoffs go when you get down to it."
But their third-period shortcomings were a primary focus on Saturday. They had one shot on goal in the final 3:28.
How can the Ducks have a stronger finish in Game 6?
"Maybe make a little more space between them and us before we get to that area," coach Randy Carlyle said. "When you play in the conference final, you're not playing against chopped liver here. There's good teams and good structure and hard-working teams. To get here, it takes a lot of fortitude, and to some degree, you're playing against teams that have earned the right to be here.
"So I don't look at it as that's a huge negative. All I know is they have a 3-2 lead. We're going into their building, and we've won there before. So I feel like our group can go into any building and play well and give us a chance for success."
Center Ryan Kesler has one point in five games against Nashville and has one goal in 16 games in the playoffs, against the Oilers in Game 3. Forward Andrew Cogliano has zero points against the Predators and Getzlaf has been scoreless in four of the five games in this series, including the past three.
