The defenseman was considered one of the most likely players to be dealt before Monday’s 3 p.m. EST deadline. Petry can become an unrestricted free agent this summer.
In exchange for the 27-year-old player, Montreal sent a 2015 second-round draft choice and a conditional fifth-round pick to Edmonton.
Petry had been the subject of trade talk for several weeks. He said in an interview in Toronto last month that he’s playing for a ”contract moving forward” and wants to show he’s a ”guy that’s going to bring intensity and bring my game day in and day out.”
