Rasmus Ristolainen, Johan Larsson and Mikhail Grigorenko are heading to Rochester.
BUFFALO — The Buffalo Sabres have returned rookie defenseman Nikita Zadorov to his Canadian junior team, and demoted three players to their minor-league affiliate.
Zadorov was assigned to London of the Ontario Hockey League on Tuesday. The move came before Zadorov played his 10th NHL game, when his three-year contract would come into effect. Drafted 16th overall in June, Zadorov had a goal in seven games in Buffalo.
Rookie defenseman Rasmus Ristolainen and rookie forward Johan Larsson have been assigned to AHL Rochester. Center Mikhail Grigorenko is heading to Rochester but on a conditioning assignment. That provides the Sabres two weeks to determine whether to recall him or send Grigorenko to his junior team in Quebec.
Defenseman Mike Weber was activated from injured reserve after missing 10 games.
