That saw him miss the following game against Wales and Alasdair Strokosch came into the side, producing a powerful performance.

White had to settle for a place on the bench for the Calcutta Cup match but entered the fray in the second half to devastating effect.

The Lions forward smashed Wasps winger Sackey in centre field in a thunderous tackle which coach Frank Hadden afterwards described as the turning point of the match.

White said: "Honestly, ever since I was a youngster. When I started playing at Under-14 level, I've been good at tackling. I think timing is the most important thing.

"The easiest way to put a big hit in is when somebody is looking at where the ball is coming from and you come from the blindside where they don't see you.

"As the defender, I'll try to read where the opposition are. If there are three ball-carrying options it's impossible to pick out the one who's going to get it.

"But if there's only one ball-carrier coming round on his own, you can put all your eggs in that one basket and try to put a good shot on him. You need to be aggressive and take a gamble sometimes. But everyone can do it."
