Charlotte Motor Speedway officials are changing the schedule for the 30th annual Sprint Cup All-Star Race weekend in May.

CMS president Marcus Smith announced Tuesday that the Sprint Showdown qualifying race will move to Friday night, May 16 - the night before the All-Star Race. The race was previously held on Saturday as a prelude to the race.

Qualifying will move from Friday night to Saturday afternoon.

By moving the Sprint Showdown to Friday night, Smith says fans will get "more bang for their buck" on Friday night since they'll be able to see Sprint Cup cars and a Truck Series race on the same night.

The top two finishers in the Showdown qualify for the All-Star Race. Fans also will vote one driver into the race on Friday night.

Chip Ganassi Racing has had a preliminary discussion with Kurt Busch about running the Indianapolis 500.

Ganassi team President Steve Lauletta said Tuesday he has spoken with Busch, but the organization is not sure yet if it has the ability to field a fifth car in the May race.

Busch put his chances Monday at "70 percent" at running the 500 this year. He said his options were Andretti Autosport and one other team he declined to identify. Busch said his first choice would be to partner with Andretti because he tested with the team last season.
