Getzlaf, who's missed the past two games after suffering a lower-body injury in pregame warm-ups Thursday night in Nashville, said he hopes to play.
"Kind of just nudging things on how it reacts, and we'll see tonight," Getzlaf said, adding that he felt little discomfort.
The NHL doesn't require teams or players to specify the exact nature of injuries, and Getzlaf declined to say what part of his body is hurt or how he was injured.
He said his ability to play would not be influenced by factors such as the Ducks' comfortable 12-point lead over the San Jose Sharks in the Pacific Division with 28 regular-season games remaining.
"It's not really in my nature to be conservative. I'll play if I'm ready to play," Getzlaf said. "I'll be out there if it reacts properly."
Being out of action, he said, "is the worst feeling when you can't be out there with your guys, especially in big games like [Nashville and at Washington last week]. Nice to see our guys react well, but those are tough games to miss."
SCOUTING REPORT: Ducks assistant coach Trent Yawney scouted the Lightning in their 4-2 loss to the Kings on Saturday, watching the defending champions score three goals on nine shots against Tampa Bay goalie Ben Bishop, who was replaced after the first period by rookie Andrei Vasilevskiy.
"It looked like L.A. is back to what we know L.A. for," Yawney said.
Despite Bishop's woes, neither Yawney nor Ducks Coach Bruce Boudreau is expecting a repeat showing by the hosts, whose loss was their first in regulation at home since Dec. 9.
Tampa Bay leads the NHL with 174 goals.
"They're a dynamic team," Yawney said. "Anytime a team loses at home, they're always going to give you their best the next game. We're going to need a solid effort. We can't have any passengers in a game like this."
ANDERSEN IN GOAL: Knowing a flurry of shots are coming his way Sunday, Ducks goalie Frederik Andersen said he's embracing what he expects to be "a good challenge.
"These are the types of games you look forward to," Andersen said. "It's about going out to play, being mentally prepared."
Andersen sat out Friday's shootout loss in Washington.
"I like to play, but you can't tear up your body like that," he said after previously enduring 20 consecutive games this season. "It's going to be like that the rest of the season to make sure I don't burn out or get an injury."
LINE MOVE: The Ducks had forward Kyle Palmieri on the first line at Sunday's skate after he sat in Washington.
