The Waikato prop, weighing in at about a tonne, sent the former Bay of Plenty No 10 - that's code for the far more lightly-framed and older man - flying.
He apologised after the game, and said there were no hard feelings between Jackson and himself afterwards. But guilty he certainly was.
Watching Roger Federer in his quarter-final at the US Open yesterday, with this backdrop the thought occurred: how long will it be before a tennis player reaches up and gives the umpire a slap and jerk out of his chair?
Even the deeply unpleasant types with serious respect issues, like Ilie Nastase, John McEnroe and Jimmy Connors didn't go that far, but give it time. But it certainly won't happen while Federer is on court.
Federer has admitted that in his younger days he had vividly angry moments on court until he learned to keep a check on his temper. You could say he became a better player for it, although the old spark still flares occasionally.
You sense that this weekend is Federer's chance for an 18th grand slam. He hasn't won one since Wimbledon two years and nine majors ago.
Having no Nadal, who he seems now not to have a prayer of beating, or the out-of-sorts Andy Murray, left him with only Novak Djokovic blocking his path. Right? Gael Monfils had other ideas yesterday.
The flaky Frenchman was two sets up. Goodnight Roger? Federer, second seed, remember, saved two match points in the fourth set then ran away with it in the fifth.
So is he good enough to beat Djokovic, assuming the slender Serb sees off Japan's Kei Nishikori in their semifinal and Federer banishes Maran Cilic in their last four showdown? You doubt it, but you have to give him a fighter's chance.
In the past couple of years there have been repeated suggestions that Federer should walk away. That he's done more than enough to enshrine his name in the pantheon, so why bang on, at 33.
But why should Federer pack his racquets for the final time if he's still winning titles, being competitive against the best and ranking in the top five - and still enjoying it.
Leave him be. Raging against the dying of the light? Maybe, but there's still some life left.
Anyway, the world's greatest athletes have earned the right to choose their departure date.
