Chelsea midfielder Oscar stayed on the field, played around 30 more minutes, but was then hospitalized after being involved in a frightening collision with Arsenal goalkeeper David Ospina.
The English Premier League took a step forward at the start of the season, instituting a new protocol for players that suffered possible concussions over the course of the match.
Those new policies failed to do immediate good on Sunday, as Chelsea midfielder Oscar stayed on and played around 30 more minutes after being involved in a frightening collision with Arsenal goalkeeper David Ospina.
The initial outrage over the clash centered on the refereeing: Michael Oliver declined to give a penalty kick to Chelsea, despite Ospina showing a fair bit of recklessness in coming out for the ball, combined with the severe impact he made with Oscar.
However, soon attention turned to what you only begin to get a glimpse of at the end of the above clip. Below is NBC Sports' halftime analysis of the collision, containing video some viewers may find disturbing. The general gist: Oscar displayed telltale signs of head trauma in the immediate aftermath of colliding with Ospina. Then, inexplicably, he played the rest of the half.
Oscar was replaced by Didier Drogba at halftime, and NBC Sports soon reported that Oscar was on his way to the hospital due to concussion-like symptoms.
The EPL's new protocol mentioned above dictates that only an independent doctor can determine whether or not a player has suffered a head injury and is fit to return to the field after suffering such an injury. Yet the end result appears to be the same as it was before the new rules were enacted.
As of yet, there is no official word on Oscar's condition. The match ended in a 0-0 draw.
