The Blues' first practice in three days stopped suddenly when Jaden Schwartz went down to the ice in pain.

Schwartz was sent to the hospital and coach Ken Hitchcock said there would be no other update until Saturday morning, but it certainly didn't look or sound good.

"We're not going to know until tomorrow morning," Hitchcock said. "We sent him to the hospital to get a further evaluation and we'll have give you an exact update on time frame tomorrow."

The Blues are already without Paul Stastny, who has a broken right foot, and will be without wing Robby Fabbri for one more game because of a concussion. Fabbri skated with the team again on Friday but won't return to action until the game on Tuesday. The same goes for defenseman Kevin Shattenkirk.

The Blues have called up forward Ty Rattie from Chicago of the American Hockey League. He will play on Saturday.

The team was in the midst of a drill when the left winger slipped and fell and then collided with the goal post. Goalie Brian Elliott saw the incident play out right in front of him.

"He shot the puck and then the puck bounced off," Elliott said. "He went to reach back for the rebound, kind of lost his edge and kind of came back into me and into the mesh of the net. So I don't really know ... I haven't seen him or talked to anybody about it, so I don't know the scope of it. Hopefully he's all right.
