Zack will be back.
The Edmonton Oilers signed forward Zack Kassian to a one-year contract Thursday.
He played 36 games for the Oilers this season after being acquired in a trade from the Montreal Canadiens for goaltender Ben Scrivens in December.
Kassian was traded to the Canadiens by the Vancouver Canucks for Brandon Prust in July.
The 25-year-old was admitted into the NHL's substance abuse program after being involved in a car accident over the summer. He was reinstated Dec. 15 and immediately waived by Montreal, which facilitated the deal to Edmonton.
