The Detroit Red Wings have activated goaltender Jonas Gustavsson off injured reserve.
The Red Wings also assigned goaltender Petr Mrazek and forward Cory Emmerton to Grand Rapids of the American Hockey League.
Gustavsson is expected to be the backup to starter Jimmy Howard, but he hasn't played this season after suffering a groin injury during the preseason. He was 2-2-1 in seven appearances last season.
Howard has started all four games this season for the Red Wings, who are 2-2-0 following their 4-2 home loss to the Phoenix Coyotes on Thursday.
Emmerton, who has played in 125 games with the Red Wings over four seasons, had one assist in four games this season.
