Kiwi Shane van Gisbergen has undergone successful collarbone surgery after injuring himself in a mountain bike accident on Saturday.
The Red Bull Ampol Racing ace started the new Supercars season in style last weekend at Bathurst, winning both races to earn maximum points from the opening round.
Van Gisbergen had a plate inserted during what his team describe as a routine procedure in Brisbane, on Saturday afternoon, and they expect their charge to be raring to go in Sandown in two weeks.
The 2016 series champion was expected to drive next weekend in the GT World Challenge event oh Phillip Island, but Triple Eight have withdrawn him from the seat.
"Shane van Gisbergen is recovering from successful surgery on his collarbone after a mountain biking accident this morning," a statement read.
"The Red Bull Ampol Racing driver had a plate inserted during the routine procedure in Brisbane this afternoon and is expected to recover well.
"Van Gisbergen was due to race in the debut round of the Fanatec GT World Challenge Australia Powered by AWS series next weekend at Phillip Island.
"While medically he would likely be able to do so, the decision has been made to wait until the Sandown SuperSprint in two weeks to return to the wheel to allow more time for a smooth recovery.
"Jamie Whincup will take his seat alongside His Highness Prince Jefri Ibrahim in the no. 888 AMG GT3 Evo."
Van Gisbergen leads the championship by 33 points from Walkinshaw Andretti United's Chaz Mostert ahead of the Sandown SuperSprint later this month.
