Ehrhoff especially would be a huge loss moving forward, and Canucks coach Alain Vigneault said both Ehrhoff and Rome could possibly miss Sunday's Game 4.
McGinn received a five-minute major and a game misconduct for his hit from behind on Rome, which left the Canucks player lying on the ice bloodied.
"I had a chance to watch it on the video," Sharks coach Todd McLellan said. "Referees probably made the right call on the ice, there's no doubt about it. I don't think there was any intent on Jamie's behalf. We hope that Rome is healthy. We don't want to see that happen to anybody. Could very easily be one of our players in that situation. We do wish him well."
The Sharks got a scare when second-line center Logan Couture temporarily left the game after colliding with linemate Ryane Clowe. Couture looked woozy after the play, but he returned later in the third period.
"Logan will be fine; he'll be playing in Game 4," McLellan said.
Whole new fourth line
"I thought they did a tremendous job," McLellan said. "I thought Desi and Ginner both went in and provided lot of energy. Jammer was a calming influence on that line. I felt comfortable using them. The way the night went, with so many power plays and penalty kills back and forth, it was hard to get them probably what they deserved, which was a little more ice time."
Eager's penalties cost the Sharks in Game 2, but McLellan insisted he wasn't penalizing Eager for that.
"Ben Eager played four games against us last year and played very effectively for Chicago and didn't take any penalties," McLellan said. "He has the discipline to control himself. We just felt we would go with a different lineup. We lost our composure in Game 2. We admitted it. I think that's the first thing we needed to do. Secondly, our leadership group is pretty strong in the locker room. And it's so intense out there right now. The game, there's so much passion in it, when you're playing ahead, you're not chasing the game, the other team has a tendency to get frustrated. They were probably the exact opposite of what we were in Vancouver."
Marleau stays hot
"Things are just starting to go in," Marleau said. "I'm playing with some pretty good players, obviously. Just getting into some good areas. The puck is starting to go in."
