Stephane Robidas lay on the ice, clutching his right leg in obvious agony.
The Dallas Stars defenceman was writhing in pain after a fluke accident sent him crashing into the boards against the Chicago Blackhawks during the second period on Friday night.
The team later announced the veteran blue-liner suffered a broken leg on the play and was carried off on a stretcher.
Robidas was trying to defend against Chicago's Jonathan Toews, who attempted a centring pass that got caught up in the 36-year-old's skate, causing his leg to bend awkwardly.
