MOORESVILLE, N.C. (AP) — Ryan Newman, projected as a possible teammate for Tony Stewart on the two-time NASCAR champion's new team, will leave Penske Racing at the end of the 2008 season.

Newman's impending departure was announced Monday in a release from the Penske team.

"We want to thank Ryan for his hard work and contributions to Penske Racing over the past nine years," team owner Roger Penske said in a statement. "We wish Ryan all the best for the future and we'll continue to focus our efforts on making the Chase with Ryan and the Alltel Dodge team this season."

Newman expressed his appreciation to Penske and to the team in a statement but gave no indication where he will be racing in 2009.

Newman has been with the Penske team since making his Sprint Cup debut in 2000. He got a full-time Cup ride in 2002 and has notched 13 victories, including this year's Daytona 500.
