The club announced Monday that the Pittsburgh Penguins have put Brooks Orpikon the injured reserve list. The 33 year old Orpik got hurt during an ugly incident against Boston on Saturday.He was jumped by one of the Bruins forwards, Shawn Thornton. Orpik was thrown to the ice and punched, briefly losing consciousness before getting stretchered off. He was later admitted to a local hospital for observation.The Penguins did not release his injury, but it’s believed the veteran indeed suffered a concussion. Thornton has been suspended indefinitely pending an in-person hearing with the NHL’s Department of Player Safety.Orpik had seven points in 30 games this season and was averaging over 22 minutes per night. Losing him is huge, especially given all the injuries on the Pittsburgh blueline. The Penguins were already without Rob Scuderi(broken ankle) and Paul Martin(fractured tibia), both who are on IR.To replace Orpik, the Penquins recalled Brian Dumoulin from AHL Wilkes-Barre/Scranton.
