Johansson, 24, has enjoyed a breakout season, compiling a 13-3-3 record with a 2.19 goals-against average, a .925 save percentage and two shutouts in 20 games. The Swede represented the Amerks in Monday’s AHL All-Star Classic in Ontario, Calif.
Coach Ralph Krueger said following Tuesday’s 5-2 loss to the Ottawa Senators the Sabres would know more about Ullmark’s injury today. Ullmark left in the third period after his skate appeared to get caught in a rut in the ice, causing him to fall.
Update: The Sabres have announced Ullmark will miss three to four weeks.
The 6-foot-5, 219-pound Johansson spent most of the past two seasons with the ECHL Cincinnati Cyclones, earning occasional recalls to the Amerks.
He underwent season-ending surgery to repair a torn meniscus last February.
The Sabres drafted him in the third round in 2014, 61st overall.
