Sobotka flew from Prague to Raleigh, NC on Thursday and completed his physical around 4:30 p.m. CT. He practiced with some teammates during an optional skate on Friday and is eligible to play on Saturday, but Armstrong said it's up to the coaches for when and where he gets into the lineup.
"When he signed in the KHL, it was as a top offensive player, one that played in offensive situations," Armstrong said. "I'm looking forward to seeing how his game has evolved. I had the opportunity to watch him play on his national team in which he played a top-six role on the Czech team. I'm looking forward to seeing him come back and how his game has evolved.
"If we get the same player back that left, that's a player that was getting almost half a point-a-game, playing with a little bit of snarl," Armstrong added. "I think the game has evolved to his style of play, a little bit of quickness, he can get in on the forecheck and play with an edge. One thing we're excited about is the faceoffs. We might start with the puck a little more than we have recently."
Prior to his stint in the KHL, Sobotka spent four seasons with the Blues, recording 101 points (29 goals, 72 assists) in 247 regular season games and eight points (one goal, seven assists) in 21 playoff games.
Overall, the Trebic, Czech Republic, native has appeared in seven NHL seasons, accumulating 123 points (35 goals, 88 assists) in 381 career regular season games and 12 points (three goals, nine assists) in 40 career playoff games.
