Calgary Flames general manager Brad Treliving had an injury update for reporters in Philadelphia this afternoon, and it was not good.

Flames captain – and the team’s best player – Mark Giordano is to undergo surgery for a torn biceps tendon and will likely be done for the season. Treliving shared the news at his media scrum following the trade deadline, noting that the surgery typically has a 4 to 5 month recovery period.

It’s obviously devastating news for a Calgary Flames group that has really overachieved this season, riding sky-high shooting percentages and relying upon huge late-game comebacks. Giordano was a huge part of both of those phenomena, with Giordano being integral to their odd-man rushes by jumping into the play and leading the charge into the offensive zone.

It’s the second straight season that Giordano’s missed significant time due to injury – and third season in the past four. The 31-year-old has been considered a Norris Trophy front-runner all season long, amassing a career-high 48 points in 61 games before being injured against the New Jersey Devils.

Heading back into action tomorrow night against the Philadelphia Flyers, the Flames are sitting in a playoff spot. Now with 20 games remaining, the challenge for this group will be making the playoffs without their locker room (and on-ice) leader.
