Rugby Union: Scotland robbed.
White insists the decision to disallow a try by Chris Paterson cost Scotland the game as they slumped to a 29-15 defeat in Port Elizabeth on Saturday.
White believes it was the Tony Spreadbury decision to chalk off Paterson's try which was the turning point in the match, allowing the Boks to go on to complete their 2-0 series success.
White said: "It was hard to be forced to trudge back 80 metres after cutting off our celebrations for Chris' try.
"That was the key moment. We thought we had got the try that could have won it for us - and suddenly it is chalked off and seconds later they've scored."
