Bobrovsky suffered a fractured finger when he was struck by a puck in practice on Monday. He is 4-4-0 with a 2.81 goals-against average and .908 save percentage in eight games this season.
The club placed the 2013 Vezina Trophy winner as the NHL's best goalie on injured reserve and added goaltender Anton Forsberg on emergency recall from its American Hockey League affiliate in Springfield, Massachusetts.
The 21-year-old Forsberg, Columbus' sixth pick and the 188th overall in the 2011 draft, did not play in two games as Bobrovsky's backup earlier this season. The Swede is 1-2-0 with a 2.36 goals-against average and .921 save percentage at Springfield.
