Concussion in the spotlight after Anthony Martial incident

Brain injury charity Headway has called for an independent review of football’s approach to concussions following an incident involving Manchester United striker Anthony Martial in Sunday’s 3-1 defeat at Watford.

The France international appeared to be concussed after a clash of heads with Watford defender Daryl Janmaat in the 27th minute of the Premier League match.

Seven minutes later, a groggy-looking Martial lost the ball in the build-up to Watford’s opener and four minutes after that he was substituted.
