A blocked shot injured Giordano early in the 2013–14 season as he suffered a broken ankle in late October. He missed 18 games due to the injury, during which the Flames gained only five wins. He still recorded career highs of 13 goals and 47 points. Though he was not named to the team, Giordano's growing reputation placed him on Team Canada's short list for the 2014 Winter Olympics, and he received a first place vote (finishing 10th overall) in voting for the James Norris Memorial Trophy as the league's top defenceman.
