UEFA says concussion substitutes are not allowed in the Women’s Champions League after confusion following a head injury to Arsenal’s Beth Mead in Wednesday’s game against Ajax.

Mead was forced off after a clash of heads with Ajax defender Lisa Doorn and Arsenal boss Jonas Eidevall said he was told he could make a concussion substitution before being informed that it would not be allowed.

Brain injury charity Headway has criticized UEFA over the incident.

UEFA rules for the competition state teams can make a maximum of five substitutions within three stoppages and there are no concussion substitutions.
