The Calgary Flames are already in tough to win games with a healthy lineup.

After losing more key players to long-term injuries, life isn’t about to become any easier as they head to Southern California for a two-game road trip which begins Friday afternoon in Anaheim.

Rookie standout centre Sean Monahan will be out on a week-to-week basis with a fractured left foot and veteran defenceman Dennis Wideman is expected to miss up to two months due to a broken bone in his left hand. Wideman will require surgery and a pin put in place.

“We’re injured, but we’re not shorthanded,” head coach Bob Hartley said defiantly after Thursday’s practice at the Corral. “They’re two big parts of our team, but you can’t win with guys you don’t have in your lineup. We have trust in the guys we have and we’re going to put them on the ice, give them their responsibilities and their roles and we’re going to be pushing them.”

The Flames summoned forward Paul Byron from the AHL Abbotsford Heat, one day after recalling forward Max Reinhart from the minors.

Monahan, who is tied for the team lead with nine goals, and Wideman — the club’s leader in ice-time — join defenceman and captain Mark Giordano (broken foot) and forwards Curtis Glencross (knee) and TJ Galiardi (back spasms) on the shelf.

Wideman’s injury was suffered in the third period of Wednesday’s 3-2 loss to the Chicago Blackhawks, although he finished the game.

Monahan was hurt in practice Nov. 21, coincidentally when hit by a Wideman shot, played through it for a couple of games and even had x-rays taken, which found nothing. But he reported after the Blackhawks game it was bothering him and a CT scan found the non-displaced fracture.

“We were starting to feel good about the fact Gio was making progress and things were looking good there,” GM Jay Feaster said. “Now, to lose a guy like Dennis Wideman is a tough blow, and with the way Mony has been playing, it’s a tough guy to take out of the lineup.

“They’re not a crutch, no pun intended, to lean on. We’re going to give some guys an opportunity here to step up. We can’t worry about the guys that aren’t in our lineup. We have to find a way to win some games with the guys we do have.”
