The injury woes continue for the Calgary Flames. The team was banged up in Steel City in a 4-3 loss to the Pittsburgh Penguins on Saturday afternoon, losing veteran forward Curtis Glencross and sturdy rearguard Kris Russell, who both left the game with apparent knee injuries. “If you look at the replay from yesterday, it doesn’t look very good,” Flames bench boss Bob Hartley said Sunday after practice about Glencross. Glencross, who recently returned to action after being sidelined 15 games with a previous injury on the same left knee, fell awkwardly to the ice Saturday after hitting Pens rookie Olli Maatta, and has since been placed on injured reserve. And losing Russell will be another blow to the Flames (13-17-6), who sit in second-last place in the NHL’s Pacific division with 32 points. “When’s the last time you can remember a bad play from Kris Russell that resulted in the goal?” Hartley said. “That’s another huge loss.” But where there’s injuries, there’s opportunity. Enter Chris Breen. Since returning Nov. 25 from a conditioning stint with the Abbotsford Heat, the 6-foot-6, 225-lb. defenceman hasn’t seen any action during that span and has logged only three pro games this season.
