Philadelphia had 11 shots on goal, the fewest in a regular-season game in team history. It was outshot 17-2 in the first and 17-6 in the second.
"[Sandstrom] played great. He did nothing wrong," DeAngelo said. "Stopped breakaway, breakaway, this chance, that chance. He was really good, so it [stinks] that he has to get the loss."
Ottawa defenseman Travis Hamonic and forward Derick Brassard each left the game with a lower-body injury. Hamonic was injured on a hit by Nick Seeler at 10:55 of the first period. Brassard was injured just prior to the goal by Pinto when he got tangled up with Sandstrom.
Smith said they will be reevaluated Friday, but "it doesn't look like they'll be able to return anytime soon."
"It's tough to see," DeBrincat said. "Two important guys to our team go down. It's not an easy thing to move past, but we've got to do it anyway."
