Worrying scenes unfolded during RB Leipzig's victorious encounter with Jose Mourinho's Tottenham, after defender Nordi Mukiele was left unconscious and swallowed his tongue after being hit by the ball.
The 22-year-old was left in a heap on the floor early in the second half, after being hit in the jaw by an attempted cross.
Worried team-mates quickly gathered around the defender, who lay momentarily motionless having swallowed his tongue.
Medical staff were rapidly on the scene to treat the Leipzig star, while the game was halted and a stretcher was brought from the sidelines.
