“Yeah, absolutely,” center Ryan O’Reilly said. “I think we have great personnel here. We have so many guys who can step in and do the job. Obviously, it’s tough losing key players like that. But we’re confident. We’ve got a great group here and (have) so many guys who are able to step in and make an impact.”

Sundqvist, 25, had a breakout regular season with 14 goals and 17 assists in 74 games. He had only two goals and seven assists in 70 previous NHL games with St. Louis and Pittsburgh.

During the playoffs, Sundqvist has four goals, five assists and is tied for the team lead at plus-8. He also is a regular on the penalty kill unit.

“He’s a big part of our team,” team captain Alex Pietrangelo said. “He plays big minutes night in and night out and in every situation.”

But Pietrangelo expressed confidence that the Blues will handle this test.

“Well, it tested us last night and we did just fine,” he said, referring to Wednesday’s 3-2 overtime victory over the Bruins.

Bothered by a wrist injury, Thomas missed his first game of the playoffs, with Robby Fabbri stepping in and playing well in his first action since Game 5 of the Dallas series May 3.
