Patrick refused on Wednesday to confirm widespread reports that she's agreed to a three-year extension of her IndyCar Series contract with Andretti Green Racing.

Asked specifically about the extension, Patrick simply shook her head, not saying a word.

Patrick is considered the biggest draw in the IRL, and her interest in moving to NASCAR has been speculated on numerous times in recent years. She has a close relationship with NASCAR owner/driver Tony Stewart, and he has said Patrick will eventually make the jump he did _ from IndyCar to stock cars.

"I'm definitely looking at doing some NASCAR stuff," Patrick said, reaffirming what she's said often in recent months. "And when we figure out what that is, we'll announce it. But we haven't figured it out yet."

IRL officials have not commented about Patrick's future.

Patrick was at Homestead-Miami Speedway with several other drivers on Wednesday to test for the IndyCar finale on Oct. 10. Earlier this season, Patrick insisted she wouldn't announce anything about her future until after this season.

There's all sort of possible scenarios: Patrick could solely run the full IRL schedule in 2010, abandon IRL entirely for NASCAR, or possibly put together some sort of schedule combining IRL events with the NASCAR's second-tier Nationwide Series or truck series.

Patrick became the only woman to ever win a major open-wheel race last season in Japan. She's fifth in this year's IndyCar standings. If she maintains that spot next week _ depending on other results, she could finished as high as fourth _ it'll be her best overall finish in the IRL standings. Patrick has improved every year in IRL, going from 12th overall in 2005 to ninth in 2006, seventh in 2007 and sixth in 2008.

"There have been good sort-of stretches to this season," Patrick said. "Coming into this year, I had a whole new engineering staff, really, on my car. I've enjoyed that change. We get along really well and I think that's been a positive thing for me. I've definitely approached this year with a more positive attitude, trying to work harder on every little thing I can think of."
