UEFA want to introduce new rules that propose additional substitutions for players who have suffered knocks to the head in order to receive concussions testing.
This proposal comes after Jan Vertonghen suffered a head injury after a clash with Toby Alderweireld and Ajax goalkeeper Andre Onana during Tottenham Hotspur's Champions League semi-final first leg loss against the Amsterdam side. Vertonghen was initially treated by medical staff before returning to the match, but walked off the pitch moments later in obvious discomfort.
According to the Mirror, the football players' organisation FIFPro want to introduce changes that would allow concussed substitutes to come off.
