Manchester City defender Eric Garcia was stretchered off in the club's first Premier League match back after a collision with goalkeeper Ederson.
The Spaniard was tracking back and did not see the oncoming keeper who was also heading towards the ball.
Ederson flew into Garcia, causing a sickening clash between the two that led to the defender coming off with a neck brace.
The match was halted for roughly ten minutes as the young City star was being treated by several medics who were pitch-side at the Etihad Stadium.
