Welsh centre, Scott Williams, attempted to send Brian O'Driscoll back into last week with this huge hit.
After getting some attention from the Irish medical team, O'Driscoll got to his feet and continued with the game. It was Scott Williams who would eventually leave the game with a shoulder injury.
Will Greenwood sums it up pretty well.
Is @BrianODriscoll made of Titanium!!!? Scott Williams buries him.. And Scott Williams is the one going off! #rbs6nations
