‘Johansson, who signed a two-year contract with the Sabres in July, has four goals among 10 points in 17 games this season. He did not miss time during the Sabres’ loss to Tampa Bay last Saturday in Stockholm, finishing with one assist and three shots on goal in 19:46 of ice time. His absence will test Buffalo forward depth for the first time this season. Vladimir Sobotka is out four-to-six weeks with a lower-body injury, which forced the Sabres to recall Curtis Lazar from Rochester prior to practice Wednesday.’
