The Sharks also have injury concerns; forward Joe Pavelski was injured on his first shift of the third period after a hit along the boards from Blues defenseman Alex Pietrangelo. Forward Tomas Hertl, who took a high hit from Blues forward Ivan Barbashev in the first period, did not play in the third.

Defenseman Erik Karlsson, who did not play the final seven minutes of the second period, did not return for the third. Karlsson also looked to be struggling in the Sharks' 2-1 loss in Game 4 at St. Louis on Friday.

DeBoer did not have an update on any of the injured players.

"It's easy to sit here and say now, yeah, sure you have regrets," DeBoer said of playing Karlsson on Sunday. "I mean, hindsight's 20/20, you know? We make those decisions based on reports we get form the player and medical, and the report was he felt he could play and get through the game."
