Uruguayan defender Alvaro Pereira took a vicious knee straight to the face from Raheem Sterling, then stayed in the match after being completely dazed on the pitch.

After being attended to, Pereira angrily gestured toward the sidelines to not be subbed off and eventually came back on.
The hit was serious, though, and it begs the question whether or not Pereira should have been allowed to continue.
No way Periera should be allowed to play on here. Medic said no, ref should take control here.— Stefan Bienkowski (@SBienkowski) June 19, 2014
Retired American Taylor Twellman, who has a history of concussions, was critical of Pereira being allowed to come back on.
