Penguins’ Matheson out indefinitely with upper-body injury

PITTSBURGH (AP) — Pittsburgh Penguins defenseman Mike Matheson is out indefinitely with an upper-body injury sustained in a loss to New Jersey. Penguins head coach Mike Sullivan said Matheson is “week to week.” It is unclear when Matheson was hurt. He skated 19:04 in a 6-1 setback that marked Pittsburgh’s third straight defeat. Matheson, who has seven goals and 14 assists in 50 games this season for the Penguins, was part of Pittsburgh’s third defensive pairing alongside Chad Ruhwedel.
