The Holden Racing Team Commodore of Garth Tander and Warren Luff has officially withdrawn from the Supercheap Auto Bathurst 1000.

Damage sustained in this morning's practice accident means the Holden Commodore cannot be repaired.

Withdrawing means James Courtney, who qualified 11th and races with Greg Murphy, is anticipated tobe elevated into this afternoon's ARMOR ALL Top 10 Shootout.

Holden Racing Team Managing Director Adrian Burgess said in a team statement that chassis' main roll cage had sustained substantial damage that could not be repaired in time for tomorrow's race.

"After further assessment, it became clear that the #2 Commodore's roll cage had sustained damage beyond what we could physically repair in the time remaining before tomorrow's Bathurst 1000," Burgess said.

"It's not a decision we've taken lightly, however safety always comes first - and we're just glad that Warren is OK after his accident.

"We'll now focus our efforts on the #22 Commodore of James Courtney and Greg Murphy - and try to get a result from tomorrow's big race."

Tander said he understood the decision, and would provide support to the team during the remainder of the weekend.

"Our first concern was for Warren and it's great to know that he is ok. Missing Bathurst is disappointing, but it is what it is.

"We might not be competing tomorrow, but it's not over for HRT, there's another car still in the garage that we'll turn our attention towards and we'll do all we can to help James and Murph win the race."

The ARMOR ALL Top 10 Shootout begins at 5.10pm local time at the Supercheap Auto Bathurst 1000.
