Kurt Busch said he declined an offer from Penske Racing to replace teammate Brad Keselowski in Friday night's Nationwide Series race at Bristol Motor Speedway. Busch instead wants to focus on helping the No. 22 team prepare for Saturday night's main event.

"I thought the best opportunity for us to get our Cup program where it needed to be was to focus just 100 percent on it," Busch said. Busch replaced Keselowski in the Nationwide race at Watkins Glen two weeks ago, and earned his first series victory since 2006.
