The Penguins acquired the forwards in a trade with the Sabres for forward Dominik Kahun on Feb. 24. Sheary had a goal and assist in a 7-3 win against the Ottawa Senators on Tuesday, his first points since his return to Pittsburgh, where he played his first NHL seasons from 2015-18.
The Penguins, 1-6-0 in their past seven games after going 8-2-1 in their previous 11, are in third place in the Metropolitan Division, three points behind the Philadelphia Flyers.
Center Nick Bjugstad will be a game-time decision after missing 55 of the past 63 games because of a lower-body injury.
The Sabres, who have lost four straight after going 5-1-0 in their previous six games, have defeated Pittsburgh twice this season and look for their first season series sweep against the Penguins since 2005-06.
