The Sabres said they had too many young players and planned to change it. It wasn't idle chatter. Buffalo has started its morning skate, and 19-year-old Mikhail Grigorenko is gone along with rookies Rasmus Ristolainen, Johan Larsson and Nikita Zadorov. Though no official word has come from the Sabres, sources say Ristolainen and Larsson have been sent to Rochester. Zadorov is on his way to London of the Ontario Hockey League. Because he didn't play 10 games -- the NHL's teenage tryout limit -- the first year of his entry-level contract did not kick in. Grigorenko, in the second year of a three-year deal, is a stickier situation. The forward is the property of the Quebec Remparts, and the team already has its maximum number of two import players. Remparts coach Philippe Boucher said Monday he likes the two players he has, so the team would have 14 days to trade Grigorenko (or, if it chooses, a different import).
