BRISTOL, Tenn. - Jimmie Johnson, coming off his victory in last Sunday’s Allstate 400 at the Brickyard, has added a pair of races to his 2008 schedule.

In addition to his duties behind the wheel of the No. 48 Hendrick Motorsports Chevrolet, the two-time reigning Sprint Cup champion will make his Truck Series debut in Bristol on Aug. 20 — driving for NFL star Randy Moss. Johnson will drive the No. 81 Kobalt Tools Silverado fielded by Randy Moss Motorsports.

Johnson also will drive the No. 48 Lowe’s Chevrolet fielded by Dale Earnhardt Jr.’s JR Motorsports in the Nationwide Series race at Watkins Glen on Aug. 9.

In Nationwide, Johnson has made 88 starts, with his only victory in 2001 — his second and final full season in the former Busch Series — at Chicagoland.

“Watkins Glen and Bristol are two tracks where I really want a win,” Johnson said. “I enjoy racing (on the road course) at Watkins Glen and, for some reason always seem to be a little better there than Sonoma. We’ve had some top-fives, so, hopefully, this will put us in the win column.

“As for the trucks, I am really looking forward to that. I have never run a truck race, so it should be fun. Heck, my brother Jarit has run more than me. But it’s going to be a good time.”
