Steen was slashed on the left hand behind the net in Tuesday's preseason opener against the Dallas Stars and will miss the rest of training camp with the injury.

ST. LOUIS - Add Alexander Steen to the list of Blues who have sustained injuries in training camp.

"We knew on the bench right after it happened," Blues Head Coach Mike Yeo said. "When he came back to the bench it was an issue. (Head Athletic Trainer) Ray (Barile) came down and talked to me and told me it happened. (Steen) was sore and he was going to give it another shot. We saw what he did last year (in the playoffs), so he played the rest of the game with it.

"It's a tough injury for sure, but we'll move forward."

The Blues have also lost forward Zach Sanford for 5-6 months with a dislocated shoulder he sustained on the first day of training camp. Defenseman Jay Bouwmeester took a puck off the skate and has a fractured ankle and will be evaulated in three weeks.

In addition, Patrik Berglund (shoulder surgery) is out until December.
