ST. LOUIS -- St. Louis Blues coach Ken Hitchcock has been known as someone who will lean on veterans rather than rookies.
However, when the Blues open the regular season Thursday against the Edmonton Oilers (8 p.m. ET; SN360), they'll have three rookies in the lineup on which Hitchcock heavily will rely.
The play during training camp of rookie defensemen Joel Edmundson and Colton Parayko couldn't be overlooked, and they will form the third defense pairing against the Oilers.
Defensemen Petteri Lindbohm and Robert Bortuzzo had been expected to be the third pairing heading into the 2015-16 season.
"None of us anticipated this, including Lindbohm," Hitchcock said. "[Lindbohm] went down to the minors and didn't deserve to, but the philosophy organizational-wise is if you're not playing on a regular basis in Game 1 here, you're going to play in the minors. We had three kids earn the job to play in the National Hockey League. We'll play two, and at the end of October we'll make a decision on how they're doing knowing full well we've got a boatload of guys playing in Chicago [American Hockey League]. We've got two guys we anticipated playing who played all of last year in the National Hockey League. These two kids just played better and we want to go with it."
What does Hitchcock want to see from his two rookie defenders?
"Same as we saw in exhibition," Hitchcock said.
Forward Robby Fabbri, the Blues' first-round pick (No. 21) in the 2014 NHL Draft, will make his NHL debut Thursday. He is a close friend of Edmonton Oilers center Connor McDavid, the top pick of the 2015 draft who also will play his first NHL game Thursday.
"We're just going to come in and try and help the team as much as we can in whatever role we're put in," Fabbri said. "We just want to establish ourselves early. Opening night's the way to do it."
Edmundson, the Blues' second-round pick (No. 46) in the 2011 draft, was the last to find out he would be in the lineup. He got word from associate coach Brad Shaw after practice Wednesday.
"Nerves have been here all camp," Edmundson said. "But I think it's changed to excitement now. All during camp it was hard to sleep and whatnot. That was just all nerves, so now it's all excitement and I can't wait to get it going."
Parayko, a 2012 third-round pick (No. 86), said the fact the Blues playing two rookies together won't be an issue. They spent time playing together last season in the AHL.
"I think we're both pretty excited to play tonight," Parayko said. "... I think we're both going to be ready to play. Nerves are going to be high but we're going to have to learn off each other. We have to make sure we're working as a unit.
"... This is very exciting. It's something you look forward to as a kid. It's something you dream of. Tough to put into words almost."
