A head clash between Wolves’ Raul Jimenez and Arsenal’s David Luiz has led to experts pleading with football authorities after increased safety action.
The collision, which saw Jimenez transported to hospital with oxygen support, displeased the brain surgeons by allowing Luiz to continue to play after a head strap.
While Jimenez was later confirmed to be conscious and recovering well, the way in which Luiz was treated is deemed to be too dangerous to happen again.
“Something is not right. This cannot be allowed to continue. How many warnings does football need?" Brain injury association charity Headway stated.
Luke Griggs, deputy chief executive at Headway, said:
“Too often in football, we see players returning to the pitch having undergone a concussion assessment - only to be withdrawn a few minutes later when it is clear that they are not fit to continue.
"That is the very reason why we urgently need temporary concussion substitutes in football. You simply cannot take a risk with head injuries. They are not like muscular injuries where you can put a player back on 'to see if they can it if off'. One further blow to the head when concussed could have serious consequences.
"The question that has to be asked is had the concussion substitutes rule been in place, would Luiz have been allowed to return to the field of play? Would that extra time in the treatment room have led to a different decision being made?
"The concussion protocol clearly states that 'anyone with a suspected concussion must be immediately removed from play', while the sport continues to promote an 'if in doubt, sit it out' approach to head injuries.
"Time and time again we are seeing this rhetoric not being borne out by actions on the pitch. Something is not right. This cannot be allowed to continue. How many warnings does football need?" he added.
