Sheffield United midfielder John Fleck was taken off on a stretcher after a serious-looking incident in the second half of the Championship game at Reading.
With United leading 1-0, Fleck went down apparently unchallenged and his team-mates quickly indicated for the medics to run on the pitch to tend to him.
The 30-year-old received “urgent medical care”, the Blades said on their official Twitter account, before, after a 10-minute delay, he was taken off on a stretcher and out of the ground to a waiting ambulance.
The Royal Berkshire Hospital is a short distance from the SCL Stadium.
The match was able to resume.
