The Penguins are up to 215 man-games lost to injury, including 31 by defenseman Kris Letang. They are 21-7-3 without Letang, an example of how contributions from unlikely sources have kept them in the Metropolitan race.
Five players who were with Wilkes/Barre-Scranton in the American Hockey League at the start of the season currently are on the Penguins roster. Forwards Jake Guentzel, Carter Rowney and Oskar Sundqvist and defenseman Chad Ruhwedel played against the Sabres. Defenseman Cameron Gaunce was scratched.
Guentzel, who, according to coach Mike Sullivan, sustained a concussion against the Sabres, has been a regular in the lineup since Jan. 16, scoring 25 points (11 goals, 14 assists) in 35 games, skating on the top line with Crosby and Conor Sheary.
"They've been a dynamic line for us," Sullivan said.
Ruhwedel has played 16 straight games, including 20 or more minutes in four of the past five. He played a season-high 22:49 at Buffalo on Tuesday. He's one of 14 defensemen the Penguins have used this season.
In addition, forward Scott Wilson, who was injured during the playoff run last season, has 23 points (seven goals, 16 assists) in 69 games playing in a bottom-six role.
