NASCAR auto racing's Dario Franchitti will make his NASCAR Busch Series debut at Memphis Motorsports Park next weekend as he continues to prepare for his first full season in the NASCAR Sprint Cup in 2008.

Chip Ganassi NASCAR Team will announce today that the current IRL IndyCar Series and Indianapolis 500 champion will drive the No. 42 Dodge next Saturday in the Sam's Town 250, marking another step up in his learning process.

The Scot will make his third stock car racing start at the 0.75-mile oval where nearly a year ago Juan Pablo Montoya made his NASCAR debut for Chip Ganassi Racing and took a respectable 11th place finish.

It will be the third different car Franchitti has driven in as many outings for his new team, but this time he will have his participation guaranteed as his car, which was driven by Montoya in 17 races this year, is in the top 35 in the owners' standings.

Franchitti will be racing against some NASCAR Nextel Cup drivers, including NASCAR Busch Series points leader Carl Edwards and others such as Sterling Marlin, Jamie McMurray, JJ Yeley and David Ragan, who will travel from Atlanta where they will race their Cup cars on Sunday.
