"I got caught up in the emotion of the try," said North in a press conference. "Looking back, I feel horrendous for doing it now. Rugby's a gentleman's game and that shouldn't be involved in the game.
"It's very difficult to explain your emotions when you've scored a try. I know it was out of line with sportsmanship and rugby and feel terrible for that. I've had a lot of stick from the boys for doing that and am pretty sure it will go on for a while longer."
The Lions can win the series this weekend in Melbourne with a victory against Australia before the final Test.
