PITTSBURGH -- The depleted Penguins defense has taken another hit, as coach Mike Sullivan says defenseman Ron Hainsey is week-to-week with an upper-body injury.
The Penguins acquired the 35-year-old Hainsey just before the trade deadline. He has one assist in 10 games since joining Pittsburgh.
Pittsburgh is already missing injured defensemen Kris Letang, Olli Maatta and Trevor Daley, though all three are expected back by the playoffs.
The Penguins called up Derrick Pouliot from their AHL affiliate in Wilkes-Barre/Scranton ahead of Friday night's 6-4 win against the New Jersey Devils to fill in for Hainsey.
Center Evgeni Malkin sat out Friday with an upper-body injury. Sullivan added that Malkin, who is fifth in the NHL in scoring with 72 points, had been dealing with the injury for some time.
