The Buffalo Sabres activated forward Cody Hodgson from injured reserve, the team announced Saturday.
Buffalo also recalled Brayden McNabb from Rochester of the AHL and sent defensemen Rasmus Ristolainen and Johan Larsson to Rochester.
Center Mikhail Grigorenko was loaned to the Quebec Remparts of the Quebec Major Junior Hockey League.
Ristolainen and Grigorenko recently returned from the World Junior Hockey Championships in Malmo, Sweden. Ristolainen scored the game-winning goal in overtime for Finland in the final.
Hodgson has eight goals and 11 assists in 33 games this season. He has been out since Dec. 19 with an upper-body injury.
The Sabres' next game is Sunday at the Washington Capitals.
