Football is 'unfathomably' ignoring its own warning signs that temporary concussion substitutes are necessary, a leading brain injury charity have said, after a horrific head collision involving two Bournemouth players in their loss to Aston Villa.
Cherries team-mates Adam Smith and Tyler Adams collided at speed early in the game, though only one of the two was substituted. Smith was replaced, while Adams carried on and completed the full 90 minutes in the 4-0 defeat by Villa.
While permanent concussion substitutions are now a fixture in football, the game's lawmakers IFAB have resisted introducing the temporary option, where a player would leave the field for a more thorough examination in the privacy of the changing room.
