‘Nicolas Aube-Kubel, 28, was the odd-man out. The winger was placed on waivers and cleared Tuesday, allowing the Sabres to assign the Stanley Cup champion to the Rochester Americans. His spot in Buffalo was awarded to center Tyson Kozak, a 2021 seventh-round draft pick who has been impressive in his nine NHL games this season. Kozak likely will remain with the Sabres until Greenway is ready to return.’
