An official announcement of contract extensions for Biffle and the sponsor with RFR could come as soon as this coming week, sources said.
A team spokesman said the organization would continue its policy of not commenting on drivers' contract status until an official announcement was made.
Biffle, 44, has spent virtually his entire NASCAR career with team owner Jack Roush and won championships in the Truck and Nationwide series. He has 19 Cup series wins in 415 starts and has finished as high as second in the series standings (2005).
With Biffle and Ricky Stenhouse Jr. remaining and the addition of driver Trevor Bayne to its Cup lineup in 2015, Roush will need to expand to a four-car operation to field a team for driver Carl Edwards, whose contract is also up at the end of the season.
