Marcos Ambrose on Friday declined to discuss a report that he's considering returning to Australia to run the V8 Supercar Series for Roger Penske.
The report this week in the Brisbane Courier-Mail was fueled at Indianapolis Motor Speedway when Richard Petty said it was up to Ambrose if he wants to stay in NASCAR next season.
"If I had something to say, I'd already say it," an irritated Ambrose said.
The Australian newspaper said Penske was working with longtime Australian race team owner Dick Johnson to form a Supercar team with Ambrose as the driver. The Australian has been in NASCAR full-time since 2006, and with Richard Petty Motorsports since 2011.
"You'll have to ask him," Petty said of Ambrose's return to the No. 9 Ford. "It's probably up to him as much as anything. He's been good for Richard Petty Motorsports, we admire what he's been doing for us. It's going to be basically a decision of what does he want to do? Does he want to run all the races, just part of the races, does he want to go home? That's going to be up to him."
