The Premier League, along with other leagues and player unions, is again requesting that football's rule-makers, the International Football Association Board (IFAB), trial temporary concussion substitutes. This renewed push aims to improve player welfare by allowing more thorough medical assessments. They believe this approach offers a better solution than permanent substitutions currently in place.

IFAB has repeatedly rejected the implementation of temporary replacements, despite backing from organizations like FIFPro and the European Leagues. The Premier League argues that temporary substitutions would ensure players suspected of concussions are removed from the field for proper evaluation. Current permanent substitutions may lead to teams risking a player's health to maintain a competitive advantage.

The leagues are proposing a 10-15 minute assessment period for potentially concussed players, with a return to play only after a clear diagnosis. They cite research showing a significant percentage of players with concussions are not immediately subbed. The Premier League is ready to share data with IFAB, which could make a decision at its AGM in Cardiff.

The push for temporary substitutes follows similar initiatives in other sports, where they have demonstrably reduced the number of players returning to play with undiagnosed concussions. The Premier League is requesting a detailed rationale if the proposal is rejected. The league also has a framework to prevent misuse of substitutions for competitive advantage.
