Dale Earnhardt Jr. likely will run seven Busch Series races next season. Which races he runs in the No. 5 car is still to be determined, said his sister Kelley Earnhardt Elledge, general manager for JR Motorsports. "It will be around seven or so," Earnhardt Elledge said Wednesday. "We haven't identified where exactly and we haven't identified all of the sponsor partners."The team has not yet named a driver for the No. 88 car, where Brad Keselowski is finishing out the season and is a candidate to remain there for next year. The drivers of the No. 5 car will likely come from the Hendrick Motorsports stable. The two teams are merging their Busch operations.
