Welsh legend Jonathan Davies has claimed that full back Leigh Halfpenny could be forced into retirement unless he changes his tackling technique.
Halfpenny was withdrawn from Wales final game of the Six Nations after suffering a concussion whilst trying to tackle Italian number 8 Samuela Vunisa.
“If he gets more and more bumps on the head, there is a danger that it’s career threatening,” said Davies.
The Toulon player was taken off the pitch immediately, six minutes before half-time.
Davies, who won 37 caps for Wales, agrees Halfpenny’s head was in the wrong position for the tackle.
“His tackling technique is poor,” Davies told BBC Wales Sport’s Scrum V programme.
“He’s brave as they come. He never shirks a tackle, but I’m slightly worried now at the amount of times I see him hit his head on the wrong side.
“If you get proper tackle technique you put your head in the right place.
“A lot of players have had bangs on the head and then they’ve been told to retire and that would be a shame.”
