ST. LOUIS - Blues defenseman Alex Pietrangelo was placed on injured reserve after sustaining a right knee injury in the Blues’ 4-1 win against Minnesota on Saturday.

Pietrangelo will be re-evaluated in three weeks.

The Blues defenseman was injured following a knee-on-knee collision with Minnesota’s Charlie Coyle with 7:20 remaining in the third period. Pietrangelo was attended to on the ice but skated off on his own power.

"We’ve dealt with it all year. We’re used to it," Blues Head Coach Ken Hitchcock said of the injury. "I don’t want to say we’re numb to it, but we’ve done hell of a job in dealing with injuries to significant players. This is another one that we’ll adjust and keep going."

Through 55 games this season, the 26-year-old blueliner has posted 23 points (three goals, 20 assists).

"It’s a huge (loss). You never want to lose anybody, but he plays close to 30 minutes a night," goalie Brian Elliott said. "Whenever you lose a guy that like, that’s going to change the dynamics back there a little bit. We’re going to have to work it out and make sure guys play their role to the best of their ability."

"There’s not much you can do about it right now, but the big thing for us is just mentally move forward as quick as you can," Hitchcock said. "The experience of having gone through this with other players helps us in this one, because our guys were good in practice today, they’ve already moved on. We were able to practice today with some of the adjustments that we’re going to make offensively, defensively, pairs and everything.

"Now it’s time to play."

Pietrangelo currently ranks fourth in the NHL in average ice time (26:40).
