Biffle to remain with Roush Fenway

   NASCAR veteran Greg Biffle has agreed to a contract extension with Roush Fenway Racing, the Observer and ThatsRacin.com have learned.

   An official announcement of Biffle's extension could come as early as this weekend at Talladega (Ala.) Superspeedway, sources said.

   As recently as April 1, Biffle said he was "90 percent sure" he would re-sign with Roush and hoped to have a new deal completed by midseason.

   Biffle said he's not had an overwhelming interest to test the free-agent market, in part because of the economy, but also because of how far Roush Fenway Racing has come from this time last year.

   While Biffle is currently 18th in Sprint Cup Series points, his teammates Carl Edwards and Matt Kenseth have already won races this season.

   During his career with Roush, Biffle has won the Truck and Nationwide series championships and finished as high as second in Cup standings in 2005. He has 16 Cup wins, 20 in Nationwide and 16 in Trucks.

   A team spokesperson on Wednesday said she could not confirm Biffle had agreed to an extension.
