General manager Ray Shero said in a statement that he is excited to have an experienced goalie like Clemmensen on his coaching staff.
"Having played at every level, Scott is an excellent fit for our young goaltenders," Shero said. "We are fortunate to have someone with his experience join our staff. Additionally, he is familiar with our organization both on and off the ice."
In 191 career NHL games with the Devils, Panthers and Maple Leafs, Clemmensen posted a 73-59-24 record with a 2.79 goals-against average. He played three games with the Devils last season and 27 with Albany Devils of the AHL.
