Sources: David Ragan to stay at Roush Fenway in 2010

Roush Fenway Racing appears to have finalized their Cup driver lineup for 2010.

With Carl Edwards, Matt Kenseth and Greg Biffle all signed to long term contracts, multiple sources have told that David Ragan will be the fourth driver at the team next year.

“Absolutely, I can confirm that David Ragan will be driving for UPS in the No. 6 Roush Fenway car,” said Zak Brown, CEO of Just Marketing International, which handles the UPS marketing account.

According to NASCAR rules, RFR has to downsize from five to four teams by the end of this year.

Although he was expected to have a breakthrough year after finishing 13th in the standings in 2008, Ragan has floundered this season as is currently ranked 30th in the standings with just one top-10 finish to his credit through 19 races — which led to speculation that he could be on the way out.

Team owner Jack Roush took the initiative of placing engineer Chris Andrews on the pit box for the last five races alongside crew chief Jimmy Fennig, but Ragan still had not regained the magic he enjoyed in 2008.

Jamie McMurray, the fifth driver at RFR, is likely headed across the street from the Roush shop to Yates Racing, which is a satellite organization of RFR. However, another option appears to be a reunion with former boss Chip Ganassi.
