Kozak was recalled from AHL Rochester on Tuesday, Bill Hoppe of the Olean Times Herald reports.
Kozak will take a roster spot from Nicolas Aube-Kubel, who was waived Monday and sent to AHL Rochester on Tuesday. Kozak has scored a goal on five shots across nine appearances with Buffalo this season. Kozak will look to draw into the lineup when the Sabres host the Bruins on Tuesday.
