Former MLS MVP Taylor Twellman is calling on FIFA to implement mandatory concussion substitution rules worldwide. He warns that inconsistent protocols among nations competing in the World Cup could endanger players.

"Quite honestly, FIFA should have a concussion sub universal in all the leagues around the world," Twellman told Reuters. The broadcaster, whose playing career was cut short by post-concussion syndrome, leads the ThinkTaylor foundation, advocating for brain injury awareness.

Twellman argues that while FIFA has protocols, the organization has failed to ensure consistent application across international competitions. "I don't think FIFA's done a good enough job of educating the world and being at the forefront of changing the sport for a better way for the athletes."

FIFA's current protocol suggests a "suspect and protect" approach, requiring players with suspected concussions to be removed for assessment and not return the same day. Video review and sideline checks are encouraged.

"FIFA may have a protocol, but that doesn't mean the application of the protocol is at the same level from every team," Twellman stated.

He highlights varying medical infrastructure globally, noting that players from different countries often have vastly different understandings of brain injuries upon arriving in leagues like MLS. "It's very difficult to be that universal medical voice when some countries don't even recognise concussions in the same way."

While praising MLS for its advancements, Twellman stressed that no league should be complacent. "Everyone should have to grow, including the NFL for that matter."

His message to current players is direct: "Take responsibility for your body, your brain, control what you can control." He emphasizes the availability of information now, leaving no excuse for players not to be educated.

With over 50 MLS players expected in the World Cup, Twellman sees the tournament as an opportunity for FIFA to lead on player safety. "We've got the education, we've got the science behind it. Now we've just got to make better decisions on and off the field."
