Two Premier League matches were paused due to medical emergencies in the stands on Wednesday, with Chelsea's clash with Watford halted on 13 minutes, while the second half between Southampton and Leicester City was delayed.
Both Chelsea and Watford players were taken off the field by the referee after play was stopped following an incident in the stands at Vicarage Road.
Chelsea defender Marcos Alonso appeared to alert the referee and the medical staff on the touchline about the incident. Chelsea's medics ran across the field to help with the situation.
