Watch: Ma’a Nonu knocked out cold after sickening head on collision

In a game that would see Montpellier run out victors by 43-20, one of the main talking points centres around a clash of heads/faces that would leave Ma’a Nonu unconscious.

What makes the incident slightly more concerning is the fact that Ma’a Nonu was knocked out just last year coincidentally by Anthony Tuitavake in the same fixture.
