The Wild activated right wing Pierre-Marc Bouchard from injured reserve and reassigned defenseman Steven Kampfer to their AHL affiliate Thursday. Bouchard received final clearance from the concussion he suffered last season. They also placed center Jake Dowell, right wing Nick Palmieri and left wing Stephane Veilleux on waivers.
The Wild start the season Saturday against Colorado.
Dumba was the team's first-round draft pick this year, the 7th overall selection, and will be one of seven defensemen on the initial roster. Marco Scandella remains in the AHL while he's recovering from a groin injury.
Left wing Matt Kassian, a 6-foot-5, 247-pound enforcer, also has a spot. Coach Mike Yeo said he's important for protection of the team's stars.
