The Detroit Red Wings will be without bright spot forward Anthony Mantha, who has developed impressively this season, will miss four to six weeks with a hand injury and will undergo surgery today, according to Helene St. James of the Detroit Free Press.

Mantha injured his hand while fighting with Patrik Nemeth of the Colorado Avalanche, a game that resulted in the two-game suspension of Tyler Bertuzzi.

Mantha has picked up 14 points in 27 games this season.

The Philadelphia Flyers have announced the hiring of Chuck Fletcher as the team’s new general manager, according to a team announcement on Monday.

The New Jersey Devils have sent defenseman Steven Santini to the AHL on a conditioning loan as the 23-year old works his way back from a broken jaw, according to NHL.com’s Tom Gulitti.

Santini has played in only one game for New Jersey this season, struggling to catch on as a full-time player for the Devils, and has only played in 76 NHL games during his short career after the Devils selected him with the 42d pick in the 2013 NHL draft.
