With team-mates like this – who needs enemies? Shanghai Shenhua player Xiong Fei was knocked out after Li Jianbin bicycle-kicked him in the face during a league match this weekend.
Jianbin was attempting to acrobatically clear the ball up field, only to connect with Fei’s face, who had leapt in the air to win an aerial duel.
The stricken player was left motionless on the floor as the game continued, before the referee at last halted proceedings so the Shanghai man could receive treatment.
He was eventually stretchered from the field, but still appeared to be in a groggy state as he left the pitch.
