Fabbri was injured Saturday in the first period after being hit in front of the Blues bench by Penguins forward Carter Rowney. Fabbri collided with the boards and appeared to be in a lot of pain as he tried to get to his feet. With help from his teammates and the Head Medical Trainer Ray Barile, Fabbri was helped to the locker room and did not return to the game.
"You always worry when you hear it might be ACL and it might be a long term one, and it certainly is," said Blues forward David Perron. "He's one heck of a player for us. He creates offense, he brings the battle level up for everybody and even though he's young, he's going to be a leader on this team in the long run and he already is with his play."
"It's a very tough loss," added Blues Head Coach Mike Yeo. "I've been real impressed with Robby, I love his competitiveness. Every time he's out on the ice he's trying to make a difference and make something happen. That said, we're trying to develop the mentality of next man up. I think we have some guys in our lineup that can bite off a little bit more, bring a little more and help relieve us in his absence."
In response to the injury, the Blues have recalled forwards Kenny Agostino and Magnus Paajarvi from the Chicago Wolves. Agostino leads the AHL overall with 60 points (18 goals, 42 assists) through 48 games this season, while Paajarvi has dressed in 25 games for Chicago, posting six goals and 10 assists.
Fabbri has played in 51 games for the Blues this season, registering 11 goals and 18 assists (29 points).
