Hockey referee Cianna Lieffers suffered a painful-looking injury during Monday night's Olympic women's hockey game between the United States and Canada.
Early in the second period, Team USA forward Amanda Kessel made a sharp turn behind Canada's net. As Kessel was turning, she swung her stick in the air and it inadvertently caught Lieffers in the face.
The high stick left Lieffers with a bloody cut above her lip, forcing her to leave the game.
But the Canadian ref did return later in the period with a bandage covering up the cut and finished out the contest.
Canada wound up beating the United States 4-2.
