Teubert is expected to miss three weeks, so he could return during the Western Conference Finals or in the Calder Cup Finals if the Barons advance that far.
The Barons still have yet to play with their full complement of defensemen this year, though they expect to add another from injury for the San Antonio series in Taylor Chorney.
Chorney has not played since injuring his knee March 25 against Grand Rapids.
Arcobello credits linemates for resurgence
In the Barons' last seven games, no player has been as productive as forward Mark Arcobello.
After a six-game stretch where he had two assists and no goals, Arcobello has been hot lately, with three goals and four assists in the last seven.
Arcobello leads the Barons in playoff scoring with five points.
“I'm getting a lot of help from (linemates Tyler) Pitlick and (Hunter) Tremblay,” Arcobello said. “They're working hard down in the corners and getting me the puck in scoring areas and when I give them the puck in those areas, they're converting.”
The line combined for 12 points in the four-game series against the Aeros.
Bunz wins WHL award
Goaltender Tyler Bunz, who joined the Barons last month after finishing off his final junior season, was named the Western Hockey League's goaltender of the year this week.
For Medicine Hat, Bunz was 39-17-5 with a 2.57 goals-against average and a .921 save percentage.
Bunz has served as a third goaltender for the Barons during the playoffs so far and was recently joined by a fourth, Olivier Roy, from Stockton.
Bunz and Roy are likely to compete for a spot on the Barons roster next season.
