The Edmonton Oilers have placed forward Ryan Nugent-Hopkins on injured reserve and recalled Iiro Pakarinen from the AHL's Bakersfield Condors.
Jim Matheson of the Edmonton Journal reports that the injury is a bruised sternum and is not considered serious. In his absence, Leon Draisaitl is expected to centre the second line.
TSN's Ryan Rishaug reported Sunday that he was experiencing some bruising after taking a big hit from Brayden McNabb of the Vegas Golden Knights that sent him to the locker room.
In 46 games so far this season, Nugent-Hopkins has 16 goals and 15 assists, while Pakarinen has one assist in 18 games for the big club.
It's been a difficult season thus far for the Oilers, but they're coming off two straight wins and will be back at it Saturday against the Vancouver Canucks to kick off a five-game homestand.
In his NHL career, Nugent-Hopkins has 111 goals and 185 assists in 441 games.
