The Buffalo Sabres are looking to end a six-game losing streak (0-4-2), but will again be without Ryan O'Reilly, who will miss his fourth game with an oblique injury. They recalled Ryan's brother, center Cal O'Reilly, and forward Cole Schneider from Rochester of the American Hockey League on Saturday. Forwards Nicholas Baptiste and Evan Rodrigues were returned to Rochester on Friday. Cal O'Reilly is the leading scorer in the AHL and Schneider is tied for second. "I think it's important you put players in situations and opportunities they can help," coach Dan Bylsma said. "Cal is that guy. He's almost a point-a-game guy. He has poise and confidence with the puck. … I think he can add to that second [power-play] unit, being a poised puck guy, controlling the play, passing." Backup goaltender Anders Nilsson will start for the first time since a 2-1 overtime loss to the New Jersey Devils on Nov. 11. Nilsson is 1-2-1 with a .917 save percentage in his career against Pittsburgh. "It's still the same game and it's still the same puck you have to stop," Nilsson said. "It's not too big of a difference. Obviously they have some very skilled guys and some guys that you have to be aware of when you're on the ice." Center Johan Larsson will start on the first line between Evander Kane and Kyle Okposo for the first time this season.
