Maxim Afinogenov scored two goals and assisted on another as Buffalo beat host Atlanta last night, 4-0, in the first career shutout for rookie goalie Martin Biron.

The Sabres snapped a three-game losing streak, taking control with two goals 21 seconds apart early in the second period. The Thrashers lost for the fifth time in six games and watched rookie center Patrik Stefan crumple to the ice with another head injury.

The NHL's No. 1 overall pick went down with a minor concussion in the first period, following at least two concussions in the minor leagues. While his status was listed as day-to-day, Stefan will definitely miss tonight's game in Buffalo.
