Predators forward Filip Forsberg will need four to six weeks to recover from an unspecified upper-body injury, the team announced Wednesday. Forsberg, who suffered the injury last Friday against the Minnesota Wild, is on injured reserve and has missed the Predators’ past two games. Prior to the injury, Forsberg was among the NHL’s most durable players. He was one of nine to appear in all of his team’s regular-season games since the start of the 2014-15 season before being sidelined.
