Danica Patrick next week will formally announce her intent to move to NASCAR full-time in 2012, multiple sources with knowledge of her contract negotiations told ESPN.

Although her contracts are still being finalized, Patrick -- who has raced in both the IndyCar Series and the Nationwide series this season and last season -- will drive the No. 7 GoDaddy.com Chevrolet for the entire 2012 Nationwide Series schedule for JR Motorsports, sources said.

She also plans to enter select Sprint Cup races next season in cars prepared by Stewart-Haas Racing, with the intent to move to Sprint Cup full-time in a multiyear deal with Stewart-Haas in 2013, sources said.

Patrick is expected to make the announcement in Phoenix, where GoDaddy.com is headquartered, in a news conference currently being arranged, according to sources.

When asked Thursday about reports that a long-term NASCAR contract would soon be announced, Patrick simply said: "Sorry to bore you, but there's nothing new to report."

JR Motorsports representatives said Wednesday they have "nothing new to report."
