Eric Engels, a beat reporter for Sportsnet in Montreal, wrote that the Flyers and the Canadiens were actively discussing a trade that would've have sent Petry to Philadelphia and James Van Riemsdyk to Montreal.
It would have involved Montreal to retain a part of Petry's $6.2M salary, as his contract is running until the 2023-24 season. The Flyers would also have sent a good prospect in the trade to make it more attractive.
