The Calgary Flames have made a single line-up change from Game 3 for tonight’s Game 4, but it’s a doozy.

Per the NHL’s official game sheet for the game, the team has inserted Lance Bouma and Micheal Ferland into the line-up in place of Markus Granlund and Josh Jooris. It’s Bouma’s first game since April 7, when he was injured blocking a shot against the Arizona Coyotes, and Ferland’s first since leaving Game 1 against Anaheim with an upper body injury.

The healthy scratched regulars tonight are Tyler Wotherspoon, Corey Potter, Drew Shore, Markus Granlund and David Wolf.

Injured Flames on the outside right now are Mark Giordano, Ladislav Smid and Paul Byron.
