NASCAR star Danica Patrick announced on Tuesday that she would no longer race for Stewart-Haas Racing beyond this year.

"It has been my honor to drive for Tony Stewart, Gene Haas and everyone at Stewart-Haas Racing for the past six seasons. Together we earned a Daytona 500 pole, seven top-10 finishes and we also had some exciting racing along the way," Patrick wrote on her Facebook (FB) - Get Report page.

"My time driving for them, however, has come to an end due to a new sponsorship arrangement in 2018. Sponsorship plays a vital role in our sport, and I have been very fortunate over the course of my career, but this year threw us for a curve," Patrick continued. "Our amazing partners, such as Aspen Dental and Code 3, stepped up in a big way on short notice this year and I am incredibly grateful."

The NASCAR star's announcement follows the decision by Smithfield Foods (SFD) to become the primary sponsor at Stewart-Haas beginning in 2018. The move was said to spur changes at Stewart-Haas including the Number 10 car, driven by Patrick.
