Backstrom sustained a lower-body injury during warm-ups prior to Game 1 of the Wild's first-round Stanley Cup Playoff series against the Chicago Blackhawks. Josh Harding started and made 37 saves in the Wild's 2-1 loss. The Wild have yet to update Backstrom's injury.
Kuemper went 1-2-0 with a 2.08 goals-against average and .916 save percentage in six games, including three starts, with the Wild this season. The 22-year-old spent most of the season in the AHL, where he went 13-8-0 with a 1.88 GAA and .934 save percentage in 21 games. He was 1-1 with a 1.51 GAA and .957 save percentage in two games for Houston in the AHL playoffs.
I'm very excited about what happened today. We've worked on this deal with Toronto for a month, or over a month. It got a little bit of legs on draft day, but it really heated up last night, and we were able to complete the deal today.
