Blues forward Vladimir Sobotka will be sidelined at least two weeks after being hit by a shot in the left ankle in Monday's practice.

Sobotka left the team's practice facility on crutches and wearing a protective boot. After tests on his ankle, the Blues say it's not broken and surgery won't be needed, but Sobotka's status won't be known until he's re-evaluated in two weeks.

"It doesn't sound too serious in the sense that he's not a surgical candidate or anything like that," Blues general manager Doug Armstrong said. "But we're going to re-evaluate in a couple of weeks."

The Blues are in the middle of a stretch of four days between games. The team is not practicing today but will return to the ice Wednesday before hosting the New York Rangers on Thursday at Scottrade Center.

Armstrong, who is out of town, said the Blues haven't yet discussed calling anyone up from the club's AHL affiliate to replace Sobotka, who has two goals, 10 points and is a plus-9 this season.

"I'll re-connect with (Blues coach) Ken (Hitchcock) later today or tonight and we'll decide what we want to do ... if we want to bring somebody up and how we'll go about that for tomorrow," Armstrong said.

The Blues have 13 forwards on their roster. Winger Chris Porter was a healthy scratch in Saturday's 1-0 win over San Jose, so Porter could be inserted into the lineup for Sobotka. However, the Blues are also awaiting word on the status of Matt D'Agostini, who suffered a head injury in Saturday's game.

D'Agostini left in the second period after a collision and didn't return to the game. He was tested for a concussion, but acknowledged after the game that he was OK. He didn't practice Monday, but Hitchcock said it was because the club was following the NHL's protocol on players who possibly suffered a concussion.

Although the Blues are off today, D'Agostini was scheduled to skate on his own, see how he felt and possibly return to practice tomorrow.

"All indication are that it was just a procedural thing ... he'll be on the ice today and ready to go tomorrow," Armstrong said.
