Red alert: Josh van der Flier puts focus on tackling technique for Six Nations finale

Josh van der Flier is looking forward to the Six Nations finale. He was injured in the opening game of the 2018 Grand Slam campaign. Dan Leavy was playing in that game. The last time Ireland won a Grand slam was in 1985. Rugby has changed a lot since then. Charlie Ewels was sent off in last Saturday's Six-Nations match. Seven of last nine red cards have been for contact made around the head area. There was just one sending-off in four years of Six Nations rugby. It was two years ago when van Der Fliers was 10. Alix Popham met Nelson Mandela before the game against South Africa.
