'I'm in disbelief!' Sam Warburton slams Welsh players' tackling after Wales v France incidents

Sam Warburton has led criticism of Wales' tackling technique after Tomos Williams and Gareth Thomas both suffered head injuries in the first half of their Six Nations clash with France.

There were worrying scenes inside the first 10 minutes at the Principality Stadium after scrum-half Williams was knocked to the ground by French centre Jonathan Danty and struggled to get to his feet, clearly concussed as he staggered back to join the Welsh defence.

While Williams was soon replaced by Kieran Hardy, moments later Thomas also left the field for an HIA after colliding with Antoine Dupont, before returning to pitch and playing on.

Both players were left dazed after tackling their opposite man with their head wrapped on the wrong side, with Williams being hit in the head by Danty's leg before Thomas got a knee to the face from Dupont.

The poor technique did not escape the notice of Warburton, with the former Wales captain saying he was "in disbelief" at the standard of tackling in international rugby.

Watching a replay of the tackles while on punditry duty for the BBC, Warburton said: "That should be a left shoulder tackle. Tomos Williams' head should be on the right hand side of Danty.

"It's the same again for Gareth Thomas, he's hit him with his left shoulder, that needs to be right, his head's on the wrong side.

"Honestly, I'm in disbelief sometimes when I watch international rugby at how many players do not choose the right shoulder, they just favour a shoulder and go with it.

"It's something I think is under-coached. Being able to tackle on both shoulders is like being able to tackle on both hands. It should be a given for every player."
