3. Mohamed Haouas (France)
The tighthead prop was sent off for a sickening punch on Scotland’s Jamie Ritchie. A TMO review showed Haouas tussling with Ritchie – and then landing a flush right-hander which briefly flattened his whole face. France had been in control up until this point at Murrayfield, so he probably cost his team a chance at the Grand Slam. Stupid.
