Paajarvi played five shifts in the first period but did not return to the ice following the conclusion of his fifth at 10:44. He was hit by Nashville's Victor Bartley in the defensive zone at 10:02, but stayed on the ice following the hit.
Stewart, who got shoved into the corner boards by Patric Hornqvist midway through the second period, was lost for the third period after he also returned for a few shifts.
"We'll see how these guys are in the next couple of days," coach Ken Hitchcock said, according to the St. Louis Post-Dispatch. "We're going to need a further evaluation on this thing (Sunday) on both guys. But Paajarvi was playing great, that's the tough part. And Stewy had a great game (Friday) and he was playing well again tonight."
