When the Predators ran into a couple of undisciplined penalties in the third period, Laviolette turned to Subban to help kill the minutes.
"We kept checking with him as the game was going on, and when Matty Irwin went in the penalty box [at 13:11 of the third period], well, we hadn't used [Subban] much on the penalty killing but we told him if the game was on the line, and it was late in the game, that we would see how it was going with him and assess the situation, and that was an opportunity for him to go in and kill some minutes," Laviolette said. "He responded well with everything. He did a good job tonight."
Subban said he knew Thursday he'd be ready to play against the Oilers.
The 27-year-old, who was traded by the Montreal Canadiens to Nashville for defenseman Shea Weber last June 29, said he wasn't putting any timetable on his game returning to its best level.
Friday, he played 2:10 less than his season average of 25:03.
"I don't know," Subban said. "I'll just take it one day at a time. Just like anything else, you don't ever put a deadline on anything. You just do what you can every day."
Subban's ice time was a secondary concern for the Predators, who have been hit hard with injuries to some top performers, among them defenseman Roman Josi, who has missed three games with an upper-body injury, and forward Colin Wilson, who has missed six games with a lower-body injury.
"It definitely lifts our team," said forward James Neal, who had one of the Predators' two shootout goals on Friday. "It gives us a confidence boost knowing that we're getting our top guys back in the lineup.
"We've held our ground and won some games with a lot of guys out of the lineup and that's a credit to the guys that have gotten called up and the depth in the organization.
"Guys have moved up in their roles. When somebody comes up, somebody has to move up in their roles and situations and those guys did an unbelievable job. It's nice to see P.K. back on the ice tonight. It's good when those players start getting back from those injuries."
