He was linked with a move to Harlequins of the English Premiership after the cup.
Upon leaving the field, Burger was seen to be gesticulating and shouting at the touch judge.
The citing commissioner decided that Burger be banned for two weeks for his actions.
However, this was reduced to a two-match suspension on appeal.
Burger would return to play a key role in South Africa's World Cup triumph as the Springboks defeated England 15–6 to lift the Webb Ellis trophy for the second time in four attempts.
After an indifferent 2006 Super 14 season, during which Burger showed only flashes of the brilliance that took him to the peak of world rugby, he was to once again start in his favoured number 6 shirt ( openside flanker in South African rugby) in the national team for the upcoming expanded Tri-Nations test series against Australia and New Zealand.
However, in the Springboks' Test match against Scotland on 17 June, Burger suffered a serious neck injury.
Following successful surgery and rehabilitation, Burger returned to the Vodacom Stormers line-up on 13 January 2007, playing 55 minutes as the Stormers lost to the Bulls.
Despite the loss, Burger did show flashes of the brilliance that took him to the peak of world rugby in 2004–05.
After a shaky start to the 2007 Super 14 season, Burger inspired the Stormers to their first win of the campaign against the Chiefs as the Stormers recorded their first points of the season in a tense 21–16 victory at the Newlands Stadium.
